A Dynamic MAC protocol is developed for WCDMA wireless multimedia networks. It uses multiple slots per frame allowing multiple users to transmit simultaneously using their own CDMA codes. The proposed MAC protocol is based on contention .If there is low contention users can access any slots and if there is high level contention the owners of the slots have priority to access slots .If the owner...

An experimental investigation of hydrodynamics gas-solid flow is carried out by engaging different designs air distributor plates. analysis three plates, i.e., perforated, 45° slotted and novel hybrid plate, revealed the difference in pressure drop minimum fluidization velocities (Umf) for varying input operational variables. Umf found to be lowest perforated highest whereas plate plate. The bu...

In this work, we introduce slot selection and co-allocation algorithms for parallel jobs in distributed computing with non-dedicated resources. A single slot is a time span that can be assigned to a task, which is a part of a job. The job launch requires a co-allocation of a specified number of slots starting synchronously. The challenge is that slots associated with different CPU nodes of dist...

There are two types of speech errors those that involve interactions between two constituents and those that involve single constituents. The interaction errors are structure preserving: they implicate constituents of the same type replacing one another, and the resulting error is structurally well-formed. Interaction errors may be classified as substitutions, exchanges, anticipations, persever...

In the cyclic reservation multiple access (CRMA) scheme, nodes reserve slots in each reserve command. Cycles are then generated in sequence, each of which services the reservations made in the corresponding reserve command. Huang et al. [2,3] proposed a reservation scheme, in which nodes are partitioned into regions and slots can be reused in succeeding regions, to reduce access delays due to l...

Induction machines are perhaps the most widely used of all electric motors. They are generally simple to build and rugged, offer reasonable asynchronous performance: a manageable torque-speed curve, stable operation under load, and generally satisfactory efficiency. Because they are so widely used, they are worth understanding. In addition to their current economic importance, induction motors ...

Preserving anonymity and privacy of customer actions within a complex software system, such as a cloud computing system, is one of the main issues to be solved in order to boost private computation outsourcing. In this paper, we propose a coordination paradigm, namely oblivious assignment with m slots of a resource R (with m ≥ 1), allowing processes to compete in order to get a slot of R, while...

In this paper, we have developed a new prototype of 0.5 hp induction motor with reduced slots in rotor bar and stator core in comparison to the conventional induction motor. The conventional induction motor usually uses 30 slots of aluminum rotor bar and 36 slots in the stator core. In our developed prototype, we used 10 slots of copper rotor bar and 24 slots in the stator core. In order to eva...

The process of deregulating airlines in the United States began in earnest with the passage of the Airline Deregulation Act of 1978. The Act set in place a timetable for removing government controls on fares and entry into routes. However, airline access to airports has not been fully deregulated. In 1968, the Federal Aviation Administration (FAA) adopted the socalled "high-density rule" to com...
