This paper presents the design and development of two element slot loaded rectangular microstrip array antenna for dual band operation. The dual bands are achieved at X and Ku band of frequencies. Effect of slots of different shapes embedded on the array elements is studied experimentally for enhancing the bandwidth. It is found that by using L-shape complementary slots on the array elements an...

Four experiments examined the effect of shared skeletal structure versus content overlap on naming printed nonwords. Experiments 1-2 compared priming among nonwords sharing either skeletal structure and content (e.g., dus-DUS) or structure alone (e.g., pid-BAF) with controls that differed from the target in the number of skeleton slots (e.g., pid-BAF vs. plid-BAF). Conversely, in Experiments 3-...

The random access channels and traffic channels are utilized, respectively, for call establishment and information transmission in the uplink direction (from mobile to base station) of the Global System for Mobile communications (GSM) networks. A call is either rejected or blocked depending on its inability to succeed either in the random access channels or in the traffic channels. The optimum ...

Wireless sensor network can be employed in wide range of application areas, such as target detection and tracking, military, and environmental monitoring. Media access control protocol is one of the most critical issues for wireless sensor network. A lot of efforts have been dedicated to MAC protocol and many MAC protocols have been proposed for different purposes. In this paper, a modified TDM...

We present a model for assigning server time slots to different classes of patients. The objective is to minimize the total expected weighted waiting time of a patient (where different patient classes may be assigned different weights). A bulk service queueing model is used to obtain the expected waiting time of a patient of a particular class, given a feasible allocation of service time slots....

This paper describes the system in Vital Filtering and Streaming Slot Filling task of TREC 2014 Knowledge Base Acceleration Track. In the Vital Filtering task, The PRIS system focuses attention on query expansion and similarity calculation. The system uses DBpedia as external source data to do query expansion and generates directional documents to calculate similarities with candidate worth cit...

A novel single layer, coaxial probe feed compact triple band slotted microstrip patch antenna with modified ground plane for wireless application has been designed and analyzed. The presented antenna, occupying a compact size of 24 × 22 × 1.6mm3, embodies a rectangular slotted patch and a rectangular ground plane modified with open ended step graded slots. The step graded slots are introduced o...

Popular fault-tolerant TDMA-based protocols like TT-CAN ([Fu00] and [Mu02]), TTP ([KG93]) and FlexRay ([Fl02]) are using a static slotting scheme for bus arbitration. This paper describes a possible solution for a more flexible handling of the slotting, by providing extra time of variable length in the cycle for additional slots. These extra time is only provided if it is requested by the contr...

Gang scheduling is currently the most popular scheduling scheme for parallel processing in a time shared environment. One major drawback of using gang scheduling is the problem of fragmentation. The conventional method to alleviate this problem is to allow jobs running in multiple time slots. However, our experimental results show that simply applying this method alone cannot solve the problem ...

Introduction: The broadcast scheduling problem (BSP) is to find a collision-free scheduling of transmissions of all the stations in a minimum number of time slots. The final arrangement of the station transmissions into their allocated time slots is called a frame. Consider a packet radio network (PRN) represented by a graph G1⁄4 (V, E), where V is the set of nodes and E the set of edges. An N ...
