Web search queries are short, ambiguous and tend to have multiple underlying interpretations. To reformulate such queries, query expansion is a prominent method that leads to retrieve a set of relevant documents. In this paper, we propose an aspectbased query expansion technique for diversified document retrieval. At first, query suggestions and completions are retrieved from major commercial search engines. A frequent phrase-based soft clustering algorithm is then applied to group similar retrieved candidates into clusters. Each cluster represents different query aspect. The expansion terms are selected from the generated cluster labels for each cluster. To estimate the relevancy between the expanded query and the documents, multiple new lexical and semantic features are introduced using the content information, and word-embedding model, respectively. Finally, a linear ranking approach is employed to re-rank the documents retrieved for the original query using the extracted features. We conduct experiments on Clueweb09 document collection using TREC 2012 Web Track queries. The experimental results clearly demonstrate that our proposed aspect-based query expansion method is effective to diversify the retrieved documents and outperformed baseline and some known related methods in terms of diversity metrics ERR-IA, α-nDCG and NRBP at the cut of 20.
Web搜索查询简短、不明确，而且往往有多种潜在的解释。为了重新表述这样的查询，查询扩展是一种重要的方法，它导致检索一组相关文档。本文提出了一种基于方面的多元文档检索扩展技术。首先，查询建议和补全是从主要的商业搜索引擎中检索的。然后应用基于频繁短语的软聚类算法对相似的检索候选词进行聚类。每个集群代表不同的查询方面。从每个集群生成的集群标签中选择扩展项。为了估计扩展查询与文档之间的相关性，分别使用内容信息和词嵌入模型引入了多个新的词汇和语义特征。最后，采用线性排序方法，使用提取的特征对原始查询检索到的文档重新排序。我们使用TREC 2012 Web Track查询对Clueweb09文档收集进行了实验。实验结果清楚地表明，我们提出的基于方面的查询扩展方法在检索文档的多样性方面是有效的，并且在多样性指标ERR-IA， α-nDCG和NRBP方面优于基线和一些已知的相关方法。

In this paper design and simulation of an X-band Power Amplifier (9.3-9.9 GHz) has been carried out. This kind of amplifiers are used in various types of radars like weather warning radars, vehicle detection radars, frequency hopping radars and phased array radars. Different types of semiconductor devices are studied/ analyzed during solid state device selection phase; however both Gallium Nitride (GaN) and Gallium Arsenide (GaAs) devices are considered appropriate for this type of design. GaAs pseudomorphic induced high electron mobility transistor (pHEMT) has been used for our design. The amplifier has been optimized for low noise, moderate power output, small return loss (input & output) and low cost. The optimization has been carried out with Advance System Design software (ADS) by Agilent. Measured results at the design frequency show overall noise figure around 2.8 dB, a linear gain of 42 dB, input and output return loss over -12 dB with an associated power at 1dB gain compression point is in excess of 2930 dBm. Using mixed elements (discrete and distributed) design technique it has been confirmed that such amplifiers are easy to build and provide cost effective solution. Keywords— HEMTs, GaAs MMICs, Solid State Power Amplifier, Cascade, Radar applications

The “last mile” bandwidth bottleneck problem can be best solved by using Ethernet Passive Optical Network (EPON). EPON is a promising technology to implement the Fiber To The Home solution. Dynamic bandwidth allocation (DBA) is one of the critical issues in the design of the EPON system that has been studied by many researches. This paper introduces the fundamental concepts on EPONs, its protocol and its bandwidth allocation. We also compile and classify the research works in order to provide the state-of-art of the DBA algorithms. The advantages and disadvantages of each classification is provided. The classifications provide insightful presentations of the prior work on EPONs which will help the researches to choose the most suitable algorithm as according to the needs.

A comprehensive approach for the practical realization of silicon light-emitting devices (Si-LEDs) with emitting visible light in the 400 to 900 nm wavelength region is discussed. Prototype Si-LEDs are fabricated in the standard CMOS technology, using the same processing procedures with other components. Since fully integrated silicon photon-receivers with Si-LED on the same chip will largely improve the overall system performance, monolithic integration leads to lower cost and smaller size. Some structural details and performances of several practical two and threeterminal Si-LEDs are presented. In this paper, we report on further progress that has been made with regard to modeling of the physical processes in realizing an increase in the optical emission power, as well with regard to higher frequency modulation capability of such device. The theory of silicon optical modulation based on p-n junction in reverse bias is primarily discussed. Initial investigations indicate that the Si-LEDs have a very fast inherent modulation bandwidth capability, and the upper limit derived value for the expected maximum modulation of the device could be in the range of a few hundred GHz. According to the best of our knowledge, despite the low efficiency, the Si-LEDs show potential for on-chip electro-optical communication.

CPU scheduler is a very important key concept in operating system which affects scheduling objectives and criteria. Choosing or modifying scheduling policy for running threads depends on predefined and specific objectives and criteria. In this paper, we investigate the effectiveness of thread weight readjustment scheduler (TWRS) for multithreaded processes in multitasking operating systems from the view point of throughput. TWRS is a proportional share CPU scheduler designed for scheduling multithreaded processes. In this work, we make change kernel performance significantly by modifying just few key parameters. We propose TWRS which preallocates certain amount of CPU time to each thread of the multi-threaded processes. The scheduler was implemented and evaluated under specific hardware and software environment. According to our evaluation results, our scheduler is promising to optimize some scheduling criteria.

Precision agriculture is the implementation of the recent technology in agriculture. Huge amount of data is collected in agriculture and various techniques of data mining are used to make efficient use of it. In this paper, we have discussed how with the help of both, clustering and classification algorithms, the crop suitable for a particular piece of land can be determined. Management zone delineation is a key task in this. From a data-mining point of view this comes down to variant of spatial clustering which has a constraint of keeping the resulting clusters spatially mostly contiguous. We analyze the need to discretize and normalize the data set and the various techniques that are used for the same. Further, a comparative analysis of the algorithm is shown where it can be seen which algorithm is best suited. We also talk about the future scope of the same and how these could actually be implemented in the real life scenarios.

In solving systems of equations on parallel computers, one very important problem is load balancing, because this affects the process efficiency. One way of achieving this goal is a good partitioning of the equations system. In this work, a connection between partitioning and pseudo-cliques from graph theory is shown. A preconditioning that uses pseudo-cliques balancing is also proposed.
