25 November 2013 While online video usage has exploded internationally, Africa is lagging behind because unbroken streaming is not possible in the low-rate internet infrastructures available on the continent. But now a group of researchers from the University of Cape Town – working in a consortium with developers from the Council for Scientific and Industrial Research (CSIR) and marketing experts from East Coast Access – have come up with an innovative solution that is could change the face of mobile usage for watching video in Africa. The platform – known as Adaptive Real-Time Internet Streaming Technology (Artist) – makes unbroken video-streaming possible with the use of algorithms to adjust quality to available bandwidth. “Our aim was to find the balance between complete blockage due to congestion and acceptable picture/video quality in order to lessen the disruption to the viewing experience of the user,” says Emeritus Professor Gerhard de Jager.Accessibility De Jager, along with Associate Professor Mqhele Dlodlo, headed up the team of researchers in UCT’s Department of Electrical Engineering that developed the intellectual property for Artist. The breakthrough could have a major impact in Africa, where accessible bandwidth is still an issue. The International Telecommunication Union estimates that fixed (read: high speed) broadband penetration is less than 1% in sub-Saharan Africa, compared to about 27.2% in developed nations. For mobile subscriptions, however, Africa isn’t nearly as far behind the rest of the world as it is with high-speed broadband. The ITU reports that per 100 inhabitants, Africa has around 63.5 mobile subscriptions, while Asian regions are at 88.7, Europe is at 126.5 and the Americas are at 109.4 mobile subscriptions per 100 inhabitants.Diverse application “Potential applications for this technology are diverse – from entertainment (sports events, community TV) to education (schooling, adult education and healthcare worker training),” says Dlodlo. The company tasked with commercialising Artist is Tuluntulu, the Zulu word for “stream”. Pierre van der Hoven, Tuluntulu’s chief executive, believes the benefit of this technology is twofold: “We can go into rural [low bandwidth] areas; and, by managing the signal, we can control the cost to end-users”. The Tuluntulu app is available on Google Play Store to anyone with an Android device running version 4.0 or later. Edited version of a story first published in UCT’s Monday Monthly.

[Johannesburg, South Africa, April 15, 2019]. Brand South Africa has announced the appointment of Ms Thulisile Manzini as Acting Chief Executive Officer of Brand South Africa, with immediate effect. This comes amidst a number of organisational challenges that the organisation faced recently, amongst which is the suspension of Dr. Kingsley Makhubela as CEO, due to a number of charges currently being pursued through a disciplinary process.“We are pleased to announce Ms Manzini’s appointment as Acting Chief Executive of Brand South Africa. She is a multifaceted executive leader with more than 20 years’ experience in the public service having held various roles in the South African government. Her experience in transforming organisations and implementing turnaround strategies has contributed positively to good corporate governance, operations and administration,” says the Chairperson of Brand South Africa’s Board, Ms Khanyisile Kweyama.Prior to her appointment at Brand South Africa, Ms Manzini was the Deputy Director-General for Governance and Administration at the Department of Telecommunications and Postal Services (DTPS), a position she has held since January 2016. She was responsible for anchoring efficiencies in business operations by driving strategy, financial services, providing sound human capital management as well as overseeing legislative mandates. In addition, she managed the interface of business systems and operations, supply chain processes and internal controls through Internal Audit and other governance structures. Her portfolio included the brand positioning and corporate identity of the organisation through Communications and Marketing, as well as managing the political and administrative interface by overseeing operations in the Ministry and the Office of the Director-General.Ms Manzini has served on a number of committees within the DTPS which includes inter alia being the Chairperson of the Macro Structural Reconfiguration team, Chairperson of the Operations Committee and the Employment Equity Committee. Ms Manzini also represented the DTPS at the Governance and Administration Cluster and attends Parliamentary structures on Governance and Administration. “In 2018 the DTPS hosted a successful International Telecommunications Union (ITU) Telecom World event in South Africa, where 180 countries were represented. She was responsible for the Department’s communications strategy and coordinated strategic engagements to ensure the successful implementation of this prestigious event”, says Minister Ndabeni-Abrahams, adding that “Ms Manzini has the full support of the Ministry and Brand South Africa’s Board of Trustees, to deliver on the organisation’s mandate.”Chairperson of Brand South Africa’s Board, Ms Khanyisile Kweyama said: “We believe that Ms Manzini is the right person to drive the organisation forward during this period. Her experience has more than prepared her to fulfil this role with excellence, we are confident that she will propel the many strategic initiatives that Brand South Africa undertakes, to inspire and unify our stakeholders, partners and employees, to continue the work of building the reputation of South Africa, so as to contribute to its global competitiveness.”Manzini’s other senior and executive management roles include Acting as Director General, Chief Operations Officer, Chief of Staff, Chief Director of Corporate Services at the Department of Public Service and Administration and Head of Corporate Services at the Municipal Infrastructure Support Agency (MISA).Amongst her various qualifications, Ms Manzini holds a Bachelor’s degree in Education from the University of Zululand, a Post Graduate Diploma in Business Administration obtained at the Wits Business School, a certificate in Management Services from Pretoria Technikon, as well as a short course on Women and Leadership Development from the Singapore Management University.“Brand South Africa’s mandate is to ensure that South Africa is positively positioned, domestically and internationally. That mandate does not change. Importantly, we want to get South Africans excited again about our nation brand. Increased levels of pride and patriotism amongst South Africans are of utmost importance. I am humbled to be a part of the vision, to be a nation brand that inspires its people and is admired globally,” says Ms Manzini.Ends/////Issued by Brand South AfricaEnquiries:Thoko ModiseE-mail: [email protected]
I may be a scruffy, untrained blogger but I can still appreciate the work of traditional professional technology analysts. SageCircle is an analyst analyst firm, they track the analyst industry. Their emails and podcasts are an inspiration – dense with information and loads of fun. (If you like that kind of thing.)SageCircle has been maintaining a list of tech analysts with Twitter accounts and the list is now up to 724 active users. It’s a cool list and I thought it would be a good thing to put into TweepML, a wonderful Twitter group-creation service we reviewed earlier this month. The link for following all the analysts is below.Visit this link and you’ll find the first 500 analysts on the list. Scroll down to the very bottom of the page, enter your Twitter username and password and click follow. Of course you could also deselect people you’d rather not follow, or deselect all and just follow the ones you know or look interesting. Then at the top of the page you’ll see a bit.ly link to part 2. With three clicks of your mouse you can add the daily minute wisdom of 724 tech analysts to your life. It takes awhile for the system to add all of your new friends, and at one point I got a message that my Twitter account was temporarily suspended – but that didn’t turn out to be true. That said, open this magic box of wisdom at your own risk.Think this sounds like a bad idea? Not if you believe that online noise is good for you or you know how to use the secret weapon of the social web, effective and strategic creation of groups. 8 Best WordPress Hosting Solutions on the Market A Web Developer’s New Best Friend is the AI Wai… Related Posts marshall kirkpatrick Why Tech Companies Need Simpler Terms of Servic… Tags:#How To#web Top Reasons to Go With Managed WordPress Hosting Thanks a bunch to Carter Lusher of SageCircle, @carterlusher, for building and maintaining this list. Want to do something to help, yourself? Go create a new Twitter account, follow all these people, then follow these instructions to create an OPML file of all the analysts’ feeds using Dave Winer’s tool for that. Then, upload that OPML file to Google Reader and you’ll be able to search through the history of these analysts’ tweets, in some cases as far as 2 or 3 years back! Then post that OPML file somewhere, or send it to me, so I can share it with everyone else reading this. What would you do with 724 new analyst friends on Twitter? I’m going to spend some time with a text file of all the usernames and a Tweetdeck column. It sure would be nice if Tweetdeck supported bulk import and export of groups. In an interview yesterday, in preparation for the ReadWrite Real-Time Web Summit, John Borthwick of Betaworks (a Tweetdeck investor) said that interoperability and innovation based on groups are something the team is working on. I think this group of analysts on Twitter is just one of many examples of value that can be derived from group creation.
Cost may be a factorNor is Inverter a fan of ceiling-mounted cassette minisplits. He thinks the 2-foot-square unit would look “massive” in one of the smaller bedrooms, and he doubts he would be able to buy three cassettes and an outdoor compressor for less than $20,000.Not so, Dorsett says. He’s certain that Inverter could get a three-zone compressor and three cassettes for “well under” $20,000, possibly even less than $10,000 if he put the job out to bid. Buying the hardware on line is about $6,000, he said, and a competitive bid shouldn’t be any more than twice that, even in an expensive market like New Jersey. Units with a smaller capacity would be even less.Yes, adds Walter Ahlgrim, with enough equipment in the attic it would be possible to keep the second floor of the house cool — but don’t start there.“In my opinion, the contractor’s solution is the one that puts the most cash in the contractor’s pocket,” says Ahlgrim. “It is also the solution with the highest operating costs. Putting equipment and or ductwork in any unconditioned space is not just a bad idea, it is a stupid, dumb, and lazy idea. The real solution starts with an energy audit including blower door testing with [infrared] photography. This will help you identify and fix the air leaks and get you get the correct insulation installed. If you still have a problem, get a Manual J calculation to tell you if need more equipment or better ductwork.”Air-sealing and insulation will cost less than buying new equipment, he adds. “The real payoff will come from savings on your electric bills for years to come,” he says. “Adding more equipment will only raise your monthly bills.” Insulation and air-sealing may be to blameThere is one more preliminary before we get to that, says Yupster.“It sounds like you have an existing forced-air system in the basement. If this is the case, the likely cause of your uncomfortable rooms is a combination of things,” Yupster writes. “Poor insulation and poor air sealing will make any room uncomfortable regardless of how much energy you pump into it.”Air sealing is a particular concern, and that’s something that Inverter can solve fairly easily. With air leaks reduced, Yupster suggests calling in an HVAC contractor who can measure air flow through the ductwork to the upstairs bedrooms and correct any imbalances in the system. To do that, Inverter will have to find the right contractor.“The key is getting someone who is willing to do measurements, static pressure, flow at the register, temperature change through the system, etc.” Yupster says. “I design these systems every day and measure and commission as many systems as I can.”Plus, Yupster adds, correcting any problems with Inverter’s existing heating and cooling system may prove far less expensive than installing new equipment.“As far as your ductwork goes, often you can’t get appropriate air flow upstairs because something in the system is too restrictive,” he writes. “Sometimes it’s a high-efficiency filter, sometimes it’s a cooling coil with a high pressure drop, sometimes it’s undersized ductwork. All of these can be remedied at significantly less cost (usually) than a whole new system.”Air-sealing the house would reduce the tendency of indoor air to stratify, and thereby lower cooling loads upstairs, he adds. If the air ducts are too small, reducing the flow of air through them is one way of making them the right size, and air-sealing and insulation would allow Inverter to do that.There are other optionsDavid McNeely points to some potential problems with the ducted minisplit option, and, like other readers, suggests that Inverter have a look at some alternatives.A ducted unit will require return air in the form of a 400-square-inch grille, he says, and if Inverter wants a MERV filter in the system he should plan on a grille of about 20 inches by 25 inches. In addition, he’ll need service access, plus another 12 inches on the side where controls are located.“So that’s a lot of square footage out of a ceiling, and don’t think you can stick it in a closet or bathroom ceiling without cutting a major hole in the closet door or wall, because a 400 cfm draw requires it to come from the whole upstairs,” he says.For these and other reasons, McNeely, Yupster and Dana Dorsett all suggest that Inverter look at some alternatives, such as wall-mounted ductless minisplits or ceiling cassettes.Dorsett, for example, says three half-ton heads (6,000 Btu/hour each) would do it with one installed in each of the three bedrooms. Or, he adds, install one unit of 6,000 to 9,000 Btu/hour in the master bedroom, and a shared 9,000 Btu/hour ducted unit in a closet between the other two bedrooms.Walls that might be used for a ductless minisplit are interior walls, Inverter replies, and there’s a problem with what wall-mounted units look like. “I am aware that nothing performs as well and as efficiently as a wall unit, but it really is not an option,” he says. “There is no closet between the bedrooms that can be used, so that’s not an option either.” RELATED ARTICLES Keeping Cool in a Two-Story HouseMy House is Too HotAll About Furnaces and Duct SystemsAir Conditioner BasicsWindow-Mounted Air Conditioners Save EnergyGBA Encyclopedia: Air ConditioningUsing Ceiling Fans To Keep Cool Without AC The units seem oversizedWhat strikes Chris King first, though, is the capacity of the minisplits that the contractor has recommended. At 20,000 Btu/hour, King says, they seem “incredibly overpowered” for cooling just three bedrooms.“I also live in N.J. and use a 18,000 Btu/h unit for 1,500 square feet of 1960s poorly insulated home,” King says. “Seems like your biggest issue is that your current system is single-zone.”Each of the units the contractor recommends, however, can be dialed back to 3,800 Btu per hour, Inverter says, and the output of the outdoor condenser can be lowered to 6,000 Btu/h. That means that if both units are running, each can operate at between 3,800 and 12,000 Btu/h.Another option, he adds, would be to install a single SEZ model with a capacity of 18,000 Btu/h — but a single unit would not allow the room temperatures to be controlled separately.That said, it’s the proposed location of the units rather than their capacity that has prompted Inverter’s question. And on this count, Yupster and others are unequivocal in counseling against putting the minisplits in an uninsulated attic.“This is a terrible idea,” he says. That’s the underlying question for this Q&A Spotlight. A GBA reader named Inverter0815 lives in a two-story colonial in New Jersey that’s hard to keep comfortable in summer. In order to get the three upstairs bedrooms down to a relatively comfortable 75° in July and August, Inverter must set the thermostat on his single-zone 2 1/2-ton air conditioner to 67°.An HVAC contractor has taken a look at the house and has a recommendation, Inverter explains in this Q&A post: install two Mitsubishi SEZ model ducted minisplits in the attic. One will cool the master bedroom, the other will cool the two bedrooms where Inverter’s children sleep.There’s one snag. The attic at Inverter’s house is unconditioned.“What got me thinking is that Mitsubishi recommends installing the SEZ units in a dropped ceiling or closet,” Inverter writes. “Can these be installed in an unconditioned attic as well? The [temperature] gets up to 130° on a sunny day in the summer, so I am a little worried. Would a traditional air handler be a better idea?” Our expert’s opinionPeter Yost, GBA’s technical director, had this to say:I think Yupster and Ahlgrim have this right: This is an enclosure/ducting problem looking for a mechanical system solution. Inverter did not respond to Yupster or Ahlgrim with any information about building enclosure performance, and we don’t know enough about existing ducting to know if an approach such as Aeroseal could completely change the air delivery problem to the second floor.Inverter should be looking for:An HVAC contractor who can do a Manual J load calculation for his current home and system size and who can give him more information on his duct system.An auditor certified by the Building Performance Institute who can do a performance assessment of his enclosure. Inverter should use those results to prioritize enclosure improvements before installing any additional cooling capacity.
Leadership takes courage.The Courage To Say No: A leader needs to the courage to say no. You will have a lot of people from different quarters who want to do things that they believe in. They are good people with good intentions. But some of what they want won’t be the right thing to do or it won’t be the right time to do it. Leadership requires an ability and a willingness to say no.The Courage to Say Yes: You also need the courage to say yes. Some ideas will be so outrageous and out-of-the-box that, upon first glance, you’ll want to say no. You won’t understand the idea, and you won’t see how it fits. It takes courage to open your mind and consider something new, especially when it doesn’t look like what you already know and believe. But this is where innovation and breakthrough ideas start. Sometimes you to have the courage to say yes.The Courage to Stay the Course: Change can be a sexy idea to a leader, especially to a new leader. But oftentimes change isn’t what’s necessary. Sometimes what is necessary is leadership and execution. A leader needs the courage to say no to change for change’s sake. It takes courage to admit that execution is the real issue and to double down on what’s right.The Courage to Change Direction: Sacred cows. History. We’ve always done it this way. A leader needs the courage to change directions, even when she changes the identity of the business. When what you are doing is no longer the right thing to do, you have to make serious change. You can’t protect the status quo, because doing so endangers your enterprise. You can’t protect the sacred cows. Real change takes immense courage.The Courage to Stand Alone: Leadership is about direction and decisions. You have to determine the direction of your enterprise and you have to make the decisions, right or wrong. There will be times when you will have to stand alone. You may find yourself alone when you say no, when you say yes, when you decide to stay the course, and when you decide to change. But you are the leader, and you have to decide what is right.Be courageous.
