Concurrent programming is still challenging and difficult. “Since concurrency techniques have become indispensable for programmers who create highly available services and reactive applications, temporal dimensions of correctness introduced by concurrency, i.e., safety and liveness, are central concerns in any concurrent design and its implementation” [Lea 98]. And without expert guidance and concurrent design-pattern description, they’re expected to occasionally fail. Thus providing significant examples and paradigms for teaching good and correct style is of prime importance.

Learning concurrency paradigms is necessary but it is not sufficient. The choice of the run-time semantics must be known since it may introduce subtle design and programming errors. It is the aim of this paper to exemplify the importance of process queuing and awaking policies (whether processes are named threads or tasks) resulting from possible choices of the monitor concept implementation.

Responsive new engine provides good performance Ride comfort WORST Significant engine noise Centre rear lap belt only Non ABS braking system manual gearbox was the variant evaluated for this report and represents the entry level diesel Pajero. The standard equipment features of this vehicle are reasonably good and include air conditioning, power steering, electric mirrors and windows, radio/CD player, engine immobiliser, driver’s airbag, limited slip differential and cruise control (now standard on all Di-D models). Significantly, anti-lock brakes are not fitted to the GLX, while a passenger’s airbag is available as an option. A monocoque body shell has been used since the introduction of the NM Pajero, and aside from the new engine, the structure of the Pajero remains unaltered.

Volkswagen says that the new bodyshell has best-in-class torsional rigidity, with significantly enhanced safety qualities. The new Polo scored four stars in Euro NCAP crash tests. Everything about the body spells high quality; from the excellent paint and trim finish, to the solid feel of the doors and rear hatch when closing, and to the small panel gaps that are achieved through laser welding processes. The body, which is made from high-strength galvanized steel, carries a 12 year anti-corrosion perforation warranty. However, the Polo isn’t quite as ‘concentrated’ as it used to be. The new body, with its stylish looks, is longer, wider and taller. This has brought some welcome improvements to interior space, both for occupants and their luggage. Polo buyers can choose between three model types. There’s a base (price leader) Polo 3door, and there are S and SE variants in three and five door versions. Automatic or manual transmission is available on all models. Prices start at $19,800 for the base three-door, the S 3-door costs $20,800 and the SE 3-door is $22,500. Prices for the five-door models are $21,800 (the S) and $23,500 (the SE). Automatic transmission costs an extra $2,000. The base model comes with dual front airbags, five lap-sash seat belts and five head restraints, electro-hydraulic power steering, engine immobiliser, heated and power adjustable exterior mirrors, steering column adjustable for tilt and reach, a single CD audio system and a 60/40 split fold rear seat.

Hyundai’s latest Sonata has stepped on a few toes in the large car segment. Externally the new V6 is almost identical to its four cylinder sibling –dual tailpipes being the only clue to the extra power. Yes, they share the same attractive Euro style body, but have decidedly different personas. DISLIKES Small front seats Light coloured trim marks easily well shaped, fine for a long trip, and the centre armrest is a welcome bonus. But anyone riding in the middle might feel short-changed by the lack of support. ERGONOMICS Functional and uncluttered, the dash layout is a model of simplicity. Large instruments face the driver, with the high set audio controls just to the left. Three rotary switches look after all of your air conditioning functions. The boot and fuel cap releases are tucked away under the driver’s armrest. Thanks to its large windscreens, front and rear vision is very good, making manoeuvring easy.

The Group B RS200 rally car is now enjoying a second career as an enthusiast s track day machine Think of the most stirring motoring moments you ve ever witnessed and there ll almost certainly be a Group B episode or two in there.Group B left an impression like no other branch of motor The problem was,it left too big an impression for all the wrong reasons: deaths were an integral part,so it was no surprise when the series was canned before many of the key cars had even been fully developed. One example was the RS200,set to crush its rivals only to have the plug pulled before it had even got going. The RS200 project started in 1983;Ford needed to get a competitive rally car developed and built as quickly as It would have four-wheel drive, and a unique shape so it wouldn t immediately be obsolete.
