Sealing with Carbotech Fosroc Synthetic Resins

A survey is given on the various options to seal water ingress from strata and from concrete structures by injecting different types of resins showing the scope and limits of the individual grouts. The report covers methacrylates and polyurethane hydrogels, one and two component polyurethane resins as well as silicate isocyanate resins. The use of fast reacting two component polyurethane resins...

The cAXE: Cutting the L2 cache into protectable pieces

Under most current operating systems, a single user, running a simple pathological program, can bring an entire system to its knees. These "denial of service" attacks pose a weak link in operating system design, both micro and monolithic. Efforts at cache-friendliness, however, are not new. We offer a survey of recent efforts to prevent denial of service attacks. We then present the cache AXE s...

Adaptive DPD Modeling in DSL Customer Premises Equipment

Digital subscriber line (DSL) systems transport high-bandwidth data, such as multimedia, to service subscribers over ordinary twisted pair copper wire telephone lines. One of the important components of the DSL system is the line driver (LD) or the power amplifier (PA). The linearity of the LD is crucial to have a high-speed internet. Any non-linearity in the LD will create intermodulation dist...

Equipment repaired is equipment gained

According to WHO, at any one time, around 50 per cent of medical equipment in lowand middle-income countries cannot be used because of lack of maintenance or spare parts.1 We have found that unwillingness or inability to repair equipment and put it back in use is also a major cause. New equipment is made available by different international non-government organisations (INGOs) competing with on...
