  • Public transport is a part of the contemporary urban model. In Vietnam, the bus system is re-established a few years ago. At the same time, some maps have been published for helping the bus passengers. But these maps are still lacked of rich contents and useful functionalities. With the aim to improving the effectiveness of Hanoi public transport system, the authors have applied GIS technology for developing an information system of Hanoi bus. A logical model of the bus network consisting of 2 sub-networks and 5 cost attributes has been designed. This model serves as a basis for developing...

  • The developers chose the 8088 over the 8086 because, while the 8088 worked on a 16-bit basis internally, it only communicated with the outside world using an 8-bit data bus. Since the 8-bit DataMaster data bus already existed, the 8088 was the obvious choice. This bus connects the motherboard of the PC, where the processor and its support chips are resident, to the memory and the expansion boards, which are plugged into the expansion slots.

  • Introduction Nowadays, the communication possibilities between automation systems are a core demand and necessity, even in the case of systems of the lower performance class. Due to the large variety of communication processors, protocols and user interfaces in the SIMATIC homogenous system world (i.e. only SIMATIC systems communicate with each other) and particularly in the heterogeneous system world (i.e. SIMATIC systems communicate with “third party” automation systems) this topic is extremely complex.

  • Problem: đụng độ bus (bus conflict). Hai RAM sẽ xuất dữ liệu cùng lúc khi VXL thực hiện lệnh đọc bộ nhớ. Solution: dùng A19 làm bộ phân xử bus (bus arbiter), trong trường hợp này có thể gọi là bộ giải mã địa chỉ (address decoder).Khi A19 = 0, bộ nhớ thấp hơn được cho phép, bộ nhớ cao bị cấm. Tương tự khi A19 = 1.

  • Although the government policies are contradictory, the overall impression is that they are favorable. The plan to expand the trolley bus system was mentioned in all the five year plans since the sixth plan but this never happened The National Transportation Policy 2001 has mentioned that environmentally friendly electric vehicles shall be promoted but the government has stopped registration of new SAFA tempos in Kathmandu has been stopped. Instead, hundreds of diesel vehicles and other vehicles continue to be added every day.

  •  Compression of executable code in embedded microprocessor systems, used in the past mainly to reduce the memory footprint of embedded software, is gaining interest for the potential reduction in memory bus traffic and power consumption. We propose three new schemes for code compression, based on the concepts of static (using the static representation of the executable) and dynamic (using program execution traces) entropy and compare them with a state-of-the-art compression scheme, IBM’s CodePack.

  • Cellular automata make up a class of completely discrete dynamical systems, which have became a core subject in the sciences of complexity due to their conceptual simplicity, easiness of implementation for computer simulation, and their ability to exhibit a wide variety of amazingly complex behavior. The feature of simplicity behind complexity of cellular automata has attracted the researchers' attention from a wide range of divergent fields of study of science, which extend from the exact disciplines of mathematical physics up to the social ones, and beyond....
