African Engineers should start leading in engineering projects within Africa

By Cynthia Chiyabu Ngwengwe

Federation of African Engineering Organisation (FAEO) President Eng. Julius Riungu says engineers are regarded as important people around the world hence the need to lead through their various projects.

He said engineers are a group of people with innovative minds and it is gratifying to note that the institution chose a theme speaking to innovation and competitiveness.

Eng Riungu said the development of a country and the world at large depends on engineering professionals.
“If you don’t use your brains to innovate new devices, projects and systems and create wealth for the country then there is no one who will do that,” he said.

He said the work of engineering professionals should be to ensure that the environment is conserved which will then help enhance development for the country.

He went on to say that the role of FAEO is to promote the engineering profession in Africa and also represent the interests of Africa in the world federation of engineers.
“We want to work with all African engineering organisations to ensure that engineering in Africa is promoted and all African countries to have the same standards in infrastructure across Africa,” he said.

He said the aim of the organisation is to ensure that engineers in Zambia can be called upon around Africa to work as consultants or contractors.
Eng. Riungu also thanked the president of EIZ for the support towards FAEO activities whenever called upon.

He said EIZ is one of the strongest institutions on the African continent because of a very strong secretariat to run the business of the institution and a Headquarters under construction.

He urged the institution to continue working harder and to be felt in the community.
“The government expects you as engineers to use the resources you have been given for the benefit of the people and consider their interest.” He said.
He went on to say that there are limited resources from government but if used rightly, then the continent will develop and go forward.

Eng Riungu said Africa has become poor because people given the responsibilities to do infrastructure development have decided to abuse the responsibilities.

He urged the engineering professionals in Zambia to take the interest of the people first.
He further said there is need for discipline among African engineers if the continent is to develop.
“I urge you my fellow engineers to aim to be consultants and contractors outside Africa and change the continent of Africa by ensuring that whatever we do is http://buyviagraonlineshop.com for the good of the people,” he said.

Eng. Riungu also urged the Minister of Infrastructure to support EIZ internship programme so that young engineers are mentored and won’t have to move to other professions due to lack of experience.

He said the internship programme should be taken seriously so that students from universities and colleges will be given internship in industry for them to have experience and get employed and continue developing the country.

He further said if this is not done, then the profession will continue losing young talent to different professions.

Eng Riungu said this requires money and, for the government, it is great investment which will pay dividends in the future.
“So we are urging all the governments around Africa to consider investing in such programmes that will benefit the country.” he said.

He said FAEO is negotiating with various partners including the AU to see how engineering can be supported through providing resources that are needed.

He went on to say that the organisation has also gone into partnership with the Royal Academy of Engineering of the United Kingdom to support some of the activities.

Engineering Institution of Zambia elects new president

By Cynthia Chiyabu Ngwengwe

14th April 2018 was the day engineering professionals awaited after nomination boxes were opened and valid nominations were circulated to the members.
The day was special in that it was the day the members would vote for a new President and Council to lead the institution for the next two (2) years.

The elections which were well contested saw the position of president having three candidates comprising of Eng. Kenneth Chense, Eng. Abel Ng’andu and Eng. Sydney Matamwandi contesting the position.

Eng. Eugene Haazele and Eng. Edward Zulu contested the position of Vice President – Policy Public Relations and National Development.

The position of Vice President – Finance and Administration was contested by Eng. Wesley Kaluba, Eng. Lt.Col. Lillian Muwina and Eng Yoram Sinyangwe.

The position of Technologists` representative was contested by Teg. Shadrick Chanda and Teg. Mutima Chikasa, making the contested positions four in total with six positions going unopposed.

Contestants were given a chance to address the members and state why they were the best candidates for the positions they were contesting.

Members then voted using electronic voting gadgets which were first introduced during the southern region AGM elections.

After members voted, Eng Matamwandi emerged as the EIZ President with Eng. Haazele taking the position of Vice President – Policy, Public Relations and National Development.

The position of Vice President – Finance and Administration was won by Eng. Wesley Wyman Kaluba with Teg. Shadrick Chanda taking the position of technologists` representative.

The unopposed positions saw Eng Willian Mulusa as the Vice President for Membership and CPD, with Eng. Monica Sililo Milupi taking the position of engineers` representative.

Tec. Noah Kasanda went unopposed in the position of technicians` representative, with Cra. Cosmas Chuula taking the position of Craftspersons’ representative, Eng. Charity Chola as engineering organisations` representative and Eng Desiderius Chapewa as engineering units` representative.

In his acceptance speech, Eng Matamwandi thanked all candidates who participated in the elections for putting up a good fight.
“A fight that has given democracy a good name in EIZ because we have demonstrated that there is time to urge, time to race but once election results are declared we unite for one purpose of taking the institution to another level”, he said.

He said the new Council will always consult and engage all members in areas of their expertise.
He said the participation of more than three members on the position of president shows that EIZ is a professional body for all the members around the country.

Eng Matamwandi thanked the nominations and elections committee for organising the elections in a professional manner and said that Council shall be committed to ensuring that members act in an ethical and professional way.

“To this effect we shall constitute a disciplinary committee to take care of those that might bleach this directive”, he said.

He further thanked the minister for taking a lead in protecting the interest of the engineering profession in the country.
Eng Matamwandi said jobs being taken by foreigners are causing so much pain to members and it is gratifying that the minister is taking the first step in protecting engineering jobs.

He said as a professional body supervised by the Ministry of Infrastructure the institution shall support the various initiatives being undertaken by the Ministry to move the country forward.

“I have in mind the vision 2030. We will do our very best to make sure that the government succeeds in that endeavour; and for the vision 2064, we will do what we can. And we have read the 7th National Development Plan, a lot of what needs to be done or achieved will require the involvement of engineering professionals and our members stand ready to help government,” he said.

Eng Matamwandi further said the 59th Council has no intension of revising the policies set but to improve on them.

He then urged all the members to work with the new Council to grow the institution.

And outgoing president Eng George Sitali said he shall continue to offer his support to the new Council and the President.

He also thanked the outgoing for their dedication and service to the institution.
“The incoming Council and the president, your race has just began, and you need to ensure that this institution continues to grow”

Minister of Infrastructure called on the new Council to work together and grow the engineering profession in Zambia.

He said Council should also work in unity with the other candidates who did not make it in the election.
“Now that elections are done you all need to work as one to improve the profession in the country,” he said.

Data Evaluation in the Fog up for your enterprise operating

Now that we now have settled on analytic database methods as a very likely segment within the DBMS market to move into the particular cloud, most of us explore several currently available programs to perform the info analysis. Many of us focus on 2 classes society solutions: MapReduce-like software, and even commercially available shared-nothing parallel sources. Before considering these courses of alternatives in detail, all of us first record some preferred properties and features that these solutions ought to ideally include.

A Require a Hybrid Method

It is now clear that will neither MapReduce-like software, neither parallel databases are excellent solutions just for data analysis in the cloud. While neither option satisfactorily meets most five of our desired homes, each residence (except typically the primitive capacity to operate on protected data) has been reached by at least one of the 2 options. Consequently, a crossbreed solution that combines the particular fault threshold, heterogeneous bunch, and simplicity out-of-the-box functionality of MapReduce with the performance, performance, and even tool plugability of shared-nothing parallel database systems might have a significant effect on the fog up database industry. Another fascinating research question is tips on how to balance typically the tradeoffs in between fault patience and performance. Increasing fault patience typically signifies carefully checkpointing intermediate benefits, but this often comes at the performance expense (e. gary the gadget guy., the rate which often data can be read down disk inside the sort standard from the initial MapReduce documents is 50 % of full capacity since the identical disks are being used to write out there intermediate Chart output). A method that can change its numbers of fault threshold on the fly presented an noticed failure pace could be a good way to handle the particular tradeoff. The bottom line is that there is equally interesting investigate and system work to be done in creating a hybrid MapReduce/parallel database method. Although these types of four projects are unquestionably an important step up the route of a amalgam solution, right now there remains a purpose for a cross types solution on the systems stage in addition to in the language levels. One exciting research dilemma that would come from this kind of hybrid integration project would be how to combine the ease-of-use out-of-the-box advantages of MapReduce-like computer software with the efficiency and shared- work positive aspects that come with loading data together with creating effectiveness enhancing info structures. Pregressive algorithms are for, just where data could initially always be read straight off of the file-system out-of-the-box, nonetheless each time info is seen, progress is done towards the a large number of activities around a DBMS load (compression, index in addition to materialized enjoy creation, and so forth )

MapReduce-like program

MapReduce and connected software including the open source Hadoop, useful plug-ins, and Microsoft’s Dryad/SCOPE collection are all built to automate typically the parallelization of enormous scale information analysis work loads. Although DeWitt and Stonebraker took plenty of criticism pertaining to comparing MapReduce to database systems inside their recent questionable blog placing (many believe such a comparability is apples-to-oranges), a comparison is usually warranted since MapReduce (and its derivatives) is in fact a useful tool for carrying out data analysis in the impair. Ability to run in a heterogeneous environment. MapReduce is also carefully designed to run in a heterogeneous environment. To end of an MapReduce career, tasks which have been still in progress get redundantly executed upon other equipment, and a process is as well as as finished as soon as both the primary and also the backup achievement has completed. This restrictions the effect that will “straggler” devices can have about total predicament time, for the reason that backup accomplishments of the jobs assigned to machines could complete primary. In a group of experiments inside the original MapReduce paper, it was shown of which backup process execution elevates query functionality by 44% by alleviating the negative affect caused by slower machines. Much of the overall performance issues regarding MapReduce and the derivative methods can be attributed to the fact that these folks were not initially designed to provide as full, end-to-end info analysis methods over organized data. Their own target use cases include things like scanning by having a large pair of documents created from a web crawler and producing a web catalog over all of them. In these programs, the type data can often be unstructured including a brute force scan method over all from the data is normally optimal.

Efficiency With the cost of the extra complexity in the loading phase, parallel sources implement crawls, materialized perspectives, and compression to improve problem performance. Negligence Tolerance. Nearly all parallel repository systems restart a query after a failure. The reason is , they are usually designed for surroundings where issues take only a few hours in addition to run on a maximum of a few hundred machines. Disappointments are relatively rare in such an environment, thus an occasional concern restart is not problematic. In comparison, in a fog up computing environment, where devices tend to be less expensive, less trusted, less effective, and more several, failures tend to be common. Only a few parallel databases, however , restart a query after a failure; Aster Data apparently has a trial showing a question continuing to help with making progress because worker systems involved in the concern are killed. Ability to operate in a heterogeneous environment. Commercially available parallel databases have not involved to (and do not implement) the latest research effects on functioning directly on encrypted data. Sometimes simple operations (such like moving or copying encrypted data) usually are supported, although advanced business, such as executing aggregations on encrypted files, is not immediately supported. It should be noted, however , that it can be possible in order to hand-code security support using user defined functions. Seite an seite databases are generally designed to run on homogeneous accessories and are vunerable to significantly degraded performance if the small part of systems in the parallel cluster are performing specifically poorly.

Data Analysis in the Cloud for your organization operating

Now that we certainly have settled on analytic database methods as a probably segment from the DBMS industry to move into the particular cloud, we all explore numerous currently available programs to perform the details analysis. We focus on 2 classes society solutions: MapReduce-like software, plus commercially available shared-nothing parallel databases. Before looking at these lessons of alternatives in detail, we all first record some desired properties and features why these solutions have to ideally have.

A Call For A Hybrid Choice

It is now clear of which neither MapReduce-like software, neither parallel databases are perfect solutions with regard to data research in the impair. While not option satisfactorily meets many five in our desired houses, each property or home (except the primitive capability to operate on protected data) has been reached by at least one of the 2 options. Therefore, a hybrid solution that combines the fault threshold, heterogeneous group, and convenience out-of-the-box functionality of MapReduce with the performance, performance, and tool plugability of shared-nothing parallel data source systems perhaps have a significant impact on the cloud database marketplace. Another exciting research problem is the right way to balance typically the tradeoffs among fault patience and performance. Increasing fault threshold typically signifies carefully checkpointing intermediate effects, but this comes at the performance expense (e. grams., the rate which will data may be read off disk inside the sort standard from the main MapReduce pieces of paper is half of full potential since the similar disks being used to write out intermediate Chart output). A system that can modify its amounts of fault threshold on the fly given an recognized failure fee could be one way to handle the tradeoff. To put it succinctly that there is each interesting study and anatomist work to get done in making a hybrid MapReduce/parallel database system. Although these kinds of four assignments are unquestionably an important part of the way of a crossbreed solution, there remains a need for a crossbreed solution at the systems degree in addition to in the language stage. One interesting research issue that would control from such a hybrid integration project can be how to mix the ease-of-use out-of-the-box features of MapReduce-like software program with the performance and shared- work benefits that come with packing data and even creating performance enhancing info structures. Incremental algorithms these are known as for, in which data can initially become read immediately off of the file system out-of-the-box, nevertheless each time info is utilized, progress is done towards the various activities bordering a DBMS load (compression, index plus materialized watch creation, and so forth )

MapReduce-like software program

MapReduce and related software like the open source Hadoop, useful exts, and Microsoft’s Dryad/SCOPE stack are all made to automate typically the parallelization of large scale information analysis workloads. Although DeWitt and Stonebraker took a great deal of criticism with regard to comparing MapReduce to databases systems inside their recent debatable blog placing (many assume that such a comparability is apples-to-oranges), a comparison can be warranted as MapReduce (and its derivatives) is in fact a great tool for undertaking data examination in the fog up. Ability to work in a heterogeneous environment. MapReduce is also thoroughly designed to operate in a heterogeneous environment. Towards the end of an MapReduce employment, tasks which are still happening get redundantly executed on other machines, and a activity is ski slopes as completed as soon as possibly the primary or the backup execution has completed. This limitations the effect that “straggler” machines can have about total concern time, for the reason that backup executions of the tasks assigned to machines will certainly complete primary. In a set of experiments within the original MapReduce paper, it absolutely was shown of which backup process execution improves query performance by 44% by treating the poor affect caused by slower machines. Much of the effectiveness issues of MapReduce as well as derivative devices can be caused by the fact that they were not at first designed to be used as whole, end-to-end info analysis methods over structured data. Their very own target use cases involve scanning by way of a large set of documents created from a web crawler and producing a web index over them. In these apps, the source data is normally unstructured plus a brute drive scan approach over all belonging to the data is normally optimal.

Shared-Nothing Seite an seite Databases

Efficiency With the cost of the extra complexity in the loading phase, parallel databases implement indices, materialized views, and compression setting to improve questions performance. Error Tolerance. Many parallel repository systems reboot a query upon a failure. Mainly because they are usually designed for conditions where issues take only a few hours and run on no more than a few 100 machines. Downfalls are fairly rare in such an environment, consequently an occasional problem restart is not really problematic. As opposed, in a fog up computing surroundings, where equipment tend to be cheaper, less dependable, less powerful, and more numerous, failures are definitely common. Only some parallel databases, however , reboot a query on a failure; Aster Data reportedly has a demonstration showing a question continuing to create progress like worker nodes involved in the problem are killed. Ability to operate in a heterogeneous environment. Is sold parallel directories have not caught up to (and do not implement) the current research outcomes on functioning directly on protected data. In some instances simple procedures (such when moving or even copying encrypted data) are supported, nevertheless advanced businesses, such as undertaking aggregations in encrypted information, is not directly supported. It has to be taken into account, however , it is possible to be able to hand-code encryption support applying user defined functions. Seite an seite databases are usually designed to operate on homogeneous apparatus and are at risk of significantly degraded performance when a small subsection, subdivision, subgroup, subcategory, subclass of systems in the parallel cluster happen to be performing especially poorly. Capability to operate on protected data.

Data Examination in the Cloud for your company operating

Now that we now have settled on inferential database techniques as a very likely segment for the DBMS industry to move into the particular cloud, we all explore several currently available programs to perform the information analysis. Most of us focus on a couple of classes of software solutions: MapReduce-like software, and commercially available shared-nothing parallel databases. Before taking a look at these courses of alternatives in detail, all of us first record some wanted properties and features these solutions ought to ideally need.

A Call For A Hybrid Solution

It is now clear of which neither MapReduce-like software, neither parallel sources are best solutions just for data examination in the fog up. While nor option satisfactorily meets all of five of our own desired homes, each residence (except the particular primitive capacity to operate on protected data) is met by no less than one of the a couple of options. Therefore, a amalgam solution that combines typically the fault patience, heterogeneous group, and simplicity out-of-the-box capabilities of MapReduce with the performance, performance, and tool plugability of shared-nothing parallel repository systems might have a significant influence on the cloud database industry. Another exciting research query is tips on how to balance the tradeoffs among fault patience and performance. Making the most of fault threshold typically means carefully checkpointing intermediate results, but this comes at a performance price (e. h., the rate which data can be read away disk within the sort standard from the unique MapReduce newspaper is half full potential since the very same disks are utilized to write out intermediate Map output). A process that can alter its degrees of fault tolerance on the fly offered an observed failure cost could be a good way to handle typically the tradeoff. Basically that there is each interesting exploration and system work to get done in creating a hybrid MapReduce/parallel database system. Although these four tasks are without question an important part of the path of a amalgam solution, now there remains a need for a amalgam solution on the systems level in addition to on the language level. One exciting research dilemma that would originate from this sort of hybrid the usage project can be how to mix the ease-of-use out-of-the-box advantages of MapReduce-like program with the proficiency and shared- work positive aspects that come with launching data and even creating functionality enhancing files structures. Incremental algorithms are called for, wherever data may initially end up being read directly off of the file system out-of-the-box, although each time information is reached, progress is done towards the numerous activities around a DBMS load (compression, index plus materialized check out creation, etc . )

MapReduce-like software

MapReduce and relevant software like the open source Hadoop, useful exts, and Microsoft’s Dryad/SCOPE bunch are all created to automate typically the parallelization of large scale info analysis work loads. Although DeWitt and Stonebraker took a lot of criticism for the purpose of comparing MapReduce to databases systems within their recent controversial blog leaving your 2 cents (many assume that such a evaluation is apples-to-oranges), a comparison might be warranted considering MapReduce (and its derivatives) is in fact a useful tool for executing data examination in the impair. Ability to work in a heterogeneous environment. MapReduce is also thoroughly designed to manage in a heterogeneous environment. Into end of an MapReduce career, tasks which have been still in progress get redundantly executed in other equipment, and a activity is huge as accomplished as soon as both the primary as well as backup achievement has accomplished. This limits the effect that will “straggler” machines can have in total questions time, seeing that backup executions of the jobs assigned to these machines could complete 1st. In a set of experiments within the original MapReduce paper, it was shown of which backup job execution improves query efficiency by 44% by alleviating the harmful affect brought on by slower machines. Much of the overall performance issues of MapReduce as well as derivative systems can be related to the fact that we were holding not initially designed to be applied as whole, end-to-end information analysis techniques over organized data. His or her target use cases include scanning by using a large group of documents produced from a web crawler and creating a web catalog over these people. In these software, the suggestions data is normally unstructured in addition to a brute power scan method over all for the data is generally optimal.

Shared-Nothing Parallel Databases

Efficiency On the cost of the extra complexity in the loading period, parallel databases implement indexes, materialized sights, and compression setting to improve predicament performance. Carelessness Tolerance. Nearly all parallel database systems restart a query after a failure. Simply because they are commonly designed for surroundings where questions take no greater than a few hours and run on no greater than a few hundred machines. Problems are fairly rare an ideal an environment, hence an occasional query restart is not problematic. In comparison, in a impair computing atmosphere, where equipment tend to be less expensive, less trustworthy, less powerful, and more a variety of, failures tend to be common. Not every parallel databases, however , restart a query upon a failure; Aster Data reportedly has a demo showing a question continuing to create progress like worker nodes involved in the concern are wiped out. Ability to manage in a heterogeneous environment. Is sold parallel databases have not swept up to (and do not implement) the recent research benefits on functioning directly on protected data. In some instances simple experditions (such seeing that moving or perhaps copying encrypted data) happen to be supported, but advanced businesses, such as doing aggregations upon encrypted info, is not directly supported. It should be noted, however , that must be possible in order to hand-code encryption support employing user described functions. Parallel databases are generally designed to run using homogeneous appliances and are susceptible to significantly degraded performance if the small subset of systems in the parallel cluster can be performing specifically poorly.

Data Examination in the Fog up for your enterprise operating

Now that we have settled on synthetic database systems as a likely segment of the DBMS industry to move into the particular cloud, most of us explore different currently available software solutions to perform the info analysis. Many of us focus on two classes of software solutions: MapReduce-like software, and even commercially available shared-nothing parallel directories. Before looking at these classes of options in detail, most of us first list some preferred properties in addition to features the particular solutions will need to ideally experience.

A Call For A Hybrid Choice

It is now clear that will neither MapReduce-like software, neither parallel databases are great solutions pertaining to data analysis in the fog up. While none option satisfactorily meets all of five in our desired homes, each real estate (except the particular primitive ability to operate on protected data) has been reached by a minumum of one of the 2 options. Hence, a hybrid solution of which combines typically the fault patience, heterogeneous cluster, and simplicity of use out-of-the-box abilities of MapReduce with the efficiency, performance, together with tool plugability of shared-nothing parallel repository systems would have a significant influence on the fog up database market. Another exciting research query is find out how to balance typically the tradeoffs among fault threshold and performance. Maximizing fault tolerance typically implies carefully checkpointing intermediate results, but this comes at a new performance price (e. gary the gadget guy., the rate which will data could be read away disk in the sort benchmark from the main MapReduce report is half of full ability since the similar disks are being used to write out and about intermediate Map output). A system that can alter its levels of fault threshold on the fly given an detected failure rate could be one way to handle typically the tradeoff. In essence that there is each interesting homework and engineering work to become done in making a hybrid MapReduce/parallel database system. Although these kinds of four projects are without question an important part of the route of a cross solution, generally there remains a need for a amalgam solution in the systems degree in addition to at the language degree. One exciting research issue that would control from this kind of hybrid incorporation project would be how to mix the ease-of-use out-of-the-box benefits of MapReduce-like program with the productivity and shared- work benefits that come with reloading data plus creating effectiveness enhancing information structures. Pregressive algorithms these are known as for, in which data can easily initially always be read immediately off of the file system out-of-the-box, yet each time information is contacted, progress is done towards the numerous activities surrounding a DBMS load (compression, index in addition to materialized see creation, and so forth )

MapReduce-like software

MapReduce and associated software such as the open source Hadoop, useful extensions, and Microsoft’s Dryad/SCOPE collection are all created to automate the particular parallelization of enormous scale files analysis work loads. Although DeWitt and Stonebraker took plenty of criticism intended for comparing MapReduce to databases systems within their recent controversial blog leaving a comment (many think that such a evaluation is apples-to-oranges), a comparison is definitely warranted ever since MapReduce (and its derivatives) is in fact a useful tool for carrying out data evaluation in the impair. Ability to run in a heterogeneous environment. MapReduce is also cautiously designed to work in a heterogeneous environment. Towards the end of a MapReduce employment, tasks which are still in progress get redundantly executed about other equipment, and a process is notable as finished as soon as either the primary or maybe the backup performance has completed. This restrictions the effect that “straggler” machines can have about total concern time, when backup executions of the tasks assigned to machines could complete initially. In a pair of experiments in the original MapReduce paper, it had been shown that will backup task execution helps query functionality by 44% by alleviating the unwanted affect due to slower devices. Much of the overall performance issues associated with MapReduce and derivative methods can be related to the fact that these folks were not initially designed to provide as finished, end-to-end data analysis devices over organised data. The target use cases incorporate scanning through the large pair of documents manufactured from a web crawler and making a web catalog over these people. In these applications, the source data can often be unstructured plus a brute drive scan tactic over all on the data is generally optimal.
