Tracking Pollution Spots In Africa – Fasmicro FA1050X In Action

0

AFRIT is working with Fasmicro to develop a system that monitors, records and analyzes the effect of CO2 in many African cities.  This will be one of the earliest works to provide data on this issue in sub-Sahara Africa. We understand that African policymakers have been working on environmental and health issues related to CO2 emission; however, few raw data exist to help policymakers make informed decisions.

 

In the first stage of the project, the CO2 distribution in different cities will be measured over a long period of time, using a set of distributed CO2-sensors and decision system under development. Our system has the capacity to incorporate other gas sensors.  The gathered data will then be used to derive a distribution pattern of the pollution in the city.  The core of this system is embedded microelectronics and wireless module that enable wireless data transfer.

 

In the second phase of the project, the gathered data will be analyzed in order to evaluate the impacts on human health and environment. Based on those results, recommendation will be made to the corresponding governments for appropriate measures to be taken. We are developing a pricing model where cities can charge polluters based on CO2 readings from our device. No argument, data will show how much you are polluting and you will have to pay.

 

This system is developed as an open platform where the sensors could be adjusted to measure rainfall, humidity, temperature, nitrogen, phosphorus, potassium, wind speed, wind direction, etc as typical in farms. We log them and farmers can decide the states of the farm without stepping out of their homes. Just have your cellphone and you will know if it rained hundreds of miles in the farm.Yes, you can apply NPK fertilizer because the crop is not getting enough. And you know before you even have to be physically present in the farm. This is innovation and please support us. Let’s make farming in Africa a science and not ‘luck based’.

 

The project will be powered by our  FA1050X datalogger.

The following are some ways you can improve the performance of your WordPress blog. First, install WP-SuperCache so that some o ft the php files will be converted into static ones. That will give your database some well deserved rest. The impact? Faster loading.

Caching is only one part of making a website faster. Here are some other plugins that will help:

  1. WP Minify reduces the number of files served by your web server by joining Javascript and CSS files together. Alternatively you can use WPSCMin, a Supercache plugin that minifies cached pages. It does not however join JS/CSS files together.
  2. Yahoo! Yslow is an extension for the Firefox add-on Firebug. It analyzes web pages and suggests ways to improve their performance based on a set of rules for high performance web pages. Also try the performance tools online at GTMetrix.
  3. Use Google Libraries allows you to load some commonly used Javascript libraries from Google webservers. Ironically it may reduce your Yslow score.
  4. The CDN Sync Tool plugin will help upload files to Amazon S3/Cloudfront if you would rather not depend on origin pull. See the plugin support forum if you have any queries about this plugin.
  5. Advanced users only: Speed up your site with Caching and cache-control explains how to make your site more cacheable with .htaccess rules.
  6. Advanced users only: Install an object cache. Choose from Memcached, XCache, eAcccelerator and others.

Why Public Utilities In Africa Are Broken And May Remain So Until They Can Attract Talents

0

During series of workshops and seminars across Africa, we asked groups of students where they would like to work upon graduation.  At Universality of Nairobi (Kenya), none of the engineering students we spoke with showed any interest to work in the public utilities. At Ahmadu Bello University (Nigeria), the brightest of the engineering students noted that public utilities like Nigeria’s PHCN (public electricity corporation) and NITEL (public telecom corporation) were lasts on their lists. From Uganda to Cameroon, Senegal to Botswana; government agencies are not attracting the very bests of African talents.  These students do not see public utilities as places to build their careers.

 

In a seminar in Benin, we made this observation to students: “why do you complain when there is no light considering that the very best among you are not interested in helping to provide that light”. They all smiled and said it was none of their problems.  We gave a lecture making an argument that any sector that cannot recruit and retain the bests in the land cannot compete. It does not matter whether this sector is run by government (many public utilities are still monopolies in Africa) or the private sector.

 

The point is that we cannot necessarily expect the governments to give us the best service on electricity, water, etc when the brightest people do not engage in those areas.  When they hire third class graduates, they cannot provide a first-grade service. It is the same analogy where a school district asks a teacher to provide A students when the teacher him/herself is not an A grade quality. It is a vicious cycle and can only be broken by getting the right talents in the pipeline.

 

The best African technical graduates are employed by banks and MNCs. The few more ambitious and risk taking ones travel abroad. Usually, the ones that make it abroad are above average; at least they pass the visa interviews. Under these conditions, the monopolistic public utilities have to plan with some graduates who may not be on top of their games. (Certainly, we do not claim that all those that work in public utilities are not bright; we are discussing averages here. We are aware of first class graduates in these agencies, though we acknowledge that those might have been hired more than a decade ago.)

 

So how do you fix this problem?

 

That is a big question because public utilities are not efficiently managed and lack dynamism you will see in banking or MNCs. The bureaucracy is stifling with usually below average remuneration. To compound all is that many African governments do not see talent drains in the utilities as a problem they have to find a solution.

 

It makes one laugh when governments issue orders that public utilities in different African countries would double capacity. Nigerian governments have consistently missed targets in this yearly ritual. Great, they will do that using foreign contractors on some lucky years. But when they are gone and time to sustain that capacity, you will notice in few weeks, the system has broken. In the good old Africa when public utilities had the brightest stars from universities, competing far better than banking, many nations had better electricity and water than today.

 

It is about knowledge and skill – the greatest tool of this century. Tell your politicians that knowledge rules the world. And they must find ways to bring talented Africans to public service to move our continent forward. Revamp the system, pay them competitively, develop merit based processes and entrust our bests to run utilities and governments and this continent will be better off.

All Hail Apple, The #1 Global Smartphone Maker In 2Q2011 – The Pains Of Nokia

0

It is now official. Apple has completed what everyone had expected for months.  Nokia smartphone global shipment declined by 31% in 2Q2011, from 24.2 million units in first quarter to 16.7 million units. Year over year with 2Q2010, it was off by 30.4%.  By that and coupled with Apple’s good market performance, Apple emerged #1 in the global smartphone market, according to a new report by IHS iSuppli.

 

According to IHS iSupple, Nokia posted the worst performance among arch competitors like Apple, Samsung Electronics Co. Ltd. and and HTC Corp.  With the overall smartphone market expanding by 7.5% sequentially, Nokia’s share of shipments declined to 15.1% in the second quarter, down from 23.6% in the first quarter. Nokia’s smartphone shipments have regressed to their level of two years ago. This caused Nokia to fall to third place, losing the No. 1 ranking for the first time in the history of the smartphone business.

 

Nokia’s decline in the second quarter allowed Apple to climb one place to take the No. 1 position, although the company only slightly outperformed the overall smartphone market, with its shipments rising by 9.1 percent sequentially.  Beyond Nokia’s problems with Symbian, the company also is encountering challenges in its transition to Windows 7 as its principal operating system for smartphones. With the announcement of the transition in early 2011, Nokia eliminated any incentive for consumers and developers to buy into its existing smartphone products, which are based on its Symbian and MeeGo operating systems. That alone has precipitated the decline as not many customers want to invest in a platform that is being retired. The big question is: will Nokia ever recover?

 

Retailers Use Mobile Apps to Enhance Customer Loyalty, Says IDC

0

The retail industry is still recovery from the recession. Hope there is no other recession meanwhile.  But as the industry moves to ramp us sales even this summer, one pattern has emerged which is increasinlyg mobile apps have become a business tool to win customers. According to a leading global market research firm, IDC, customer loyalty applications and CRM innovations have  become the key drivers of retailers’ go-to-market strategies.

 

The IDC report  shows that   the top 3 customer expectations from loyalty programs are transparent management of loyalty programs, access to special services and personalized promotions, and access to a wider range of products matching personal preferences. This is where technology is making a contribution. Retailers are increasingly integrating their operations with the latest technology, including mobiles apps. In the report,  Ivano Ortis, international head of IDC Retail Insights was quoted on the importance of these apps on  enhancing operations and improving customer loyalty.

 

“The mobile targeted retailing and rewarding approach is most likely what customers expect from a leading customer-centric retailer. We believe that the ability to create and foster loyalty, enhanced by the delivery of new services, is the key issue for retailer to obtain repeated and long-term customer engagements. With better insight into demand dynamics and customer behavior provided by loyalty applications, retailers can measure the real increase of customer retention, providing an opportunity to drive repeated, larger, and more profitable customer transactions. Retailers must choose the loyalty management applications that deliver higher flexibility, scalability, and responsiveness to optimize the customer experience.”

 

It is about innovation which is the key driver of this industry. You need to find and keep the customers. In order to address consumers’ expectations and add value to the “earn points to redeem” schemes, it is imperative to look at loyalty management within its wider ecosystem.  The following are some key findings from the study.

 

 

  • Loyalty is moving beyond points and discounts to become an integral part of a more encompassing customer experience that will support same-shopper sales and gain of market share to increase or recover competitive advantage.
  • Omnichannel retailers use insights to identify and understand a core group of most valued customers. From there, they can predict what might motivate changes in shopping behavior that will make them even more loyal.
  • Mobile loyalty applications represent an element of innovation that meets customer’s demand for real-time, profile-relevant, and location-based information.
