With the increasing integration of Distributed Energy Resources (DER) in the power grid, a decentralized approach becomes essential for scheduling and allocation of resources in a smart grid. Economic Dispatch (ED) and Unit Commitment (UC) are the two major resource allocation problems that play critical role in the safe and stable operation of a grid system. The uncertainty associated with renewable...
A Holter Monitor is a device which is worn by patients and is used to collect Electrocardiography (ECG) data for around 24 hours. This device is then connected to a computer by a physician to download the data. An analysis of this data can reveal abnormalities which may not appear in a clinical measurement of shorter duration. Cost of a Holter monitor is a crucial parameter, as this is used by patients...
Broadband Internet user base is growing at an exponential pace in India. The market pressures are forcing the Internet service providers (ISPs) to sell their service offerings aggressively, resulting in a growing discrepancy between consumer expectations and service offerings from the ISPs. This discrepancy is often evident in experienced vs offered Internet connection service. We study the Quality...
Use of Graphics Processing Unit (GPU) software is increasing due to the need for data intensive operations and availability of GPUs. This has led to a need for effective GPU software verification tools. These tools have to satisfy requirements such as accuracy, reliability and ease of use. In this work, we have considered two such tools: GPU Verify and GKLEE. Our objectives were to learn about the...
Interactive journey planning on public transport networks is a challenge. We humans cope with the journey planning challenge by intuitively searching timetables for patterns. Connection scan algorithm (CSA) is a promising algorithm to automate interactive journey planning by searching timetables for best possible journey plan. We propose t-CSA algorithm as an extension of CSA. Our contribution is...
Structural Health Monitoring (SHM) is one of the important application domains of Wireless Sensor Networks (WSN) where health status of a civil structure is monitored continuously. Pipeline Monitoring is one of the important applications in the area of WSN SHM that uses a hierarchical network with heterogeneous nodes where each layer assigned different task by using different types of nodes. The main...
In this paper we propose an integrated test environment for combinatorial testing and discuss its realization at macro level. We describe the entities that make up the integrated test environment and their interaction, high-lighting the combinatorial test aspects. The proposed environment can be used for the automated as well as manual testing. Test tools supplied by research institutions and commercial...
S = 2 quantum antiferromagnetic chains described by XXZ Heisenberg Hamiltonian with uniaxial anisotropy has been studied using DMRG technique. Chains of length up to 92 have been considered keeping 50 most significant states in the density matrix. Variation of the ground-state energy and Haldane gap with anisotropy parameters is reported.
