A Pure Genetic Energy-Efficient Backbone Formation Algorithm for Wireless Sensor Networks in Industrial Internet of Things
No full textIndustry 4.0 envisions the utilization of Industrial Internet of Things (IIoT) to increase the efficiency and productivity in industrial automation and manufacturing processes. To interconnect various objects, wireless sensor networks (WSNs) are indispensable technologies located in the communication layer of IIoTs. Backbone formation is an important approach to achieve primitive operations such as data aggregation, routing and scheduling in energy-efficient WSNs. One of the fundamental backbone structures is the connected dominating set (CDS) which has been extensively studied by researchers. Although CDS provides a suitable infrastructure for relaying the sensed data packets, node energies are not primary concern during CDS construction phase. To achieve this, nodes are assigned weight values which are taken as a function of their resident energies. Weighted CDS (WCDS) problem is to find a set of nodes with minimum total weight such that every node in network is in the dominating set or a neighbor of at least one element of the dominating set. WCDS provides an energy-efficient backbone which leads to prolong the network lifetime. WCDS problem is in NP-Hard complexity class, so designing polynomial time heuristics is of utmost importance. To this aim, a pure genetic algorithm is proposed for the minimum WCDS problem on WSNs modeled as undirected graph in this paper. Each member of the population used in the algorithm is represented by a chromosome of bits where each bit indicates the corresponding node is in WCDS or not. Fitness value of a member is calculated by considering its total weight as well as the connectivity status of dominators. We analyze the time complexity of the proposed algorithm and show that our algorithm performs well in terms of total weight of the dominators, count of the dominators and the iteration count with respect to graph size, connection probability and maximum energy. © 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG

Automatic registration of structural brain MR images to MNI image space [Yaplsal Beyin MR Görüntülerinin MNI Görüntü Uzayma Otomatik Çakiştirilmasi]
No full text2015 23rd Signal Processing and Communications Applications Conference, SIU 2015 -- 16 May 2015 through 19 May 2015 -- 113052Disease diagnosis has been made by experts examining the images obtained by magnetic resonance imaging (MRI) technique, the disease process is observed using images taken at different times. Brain MR images are registered to the standard brain atlases because the human brain has a complex structure and varies from person to person. Corpus Callosum (CC) has a big importance for medical image registration because it can be easily distinguished on T1-weighted structural brain MR images and does not vary prominently between individuals. In this study, from the midsagittal brain MR image that belongs to the patient CC is detected fully automatically via Valley Matching (VM) Algorithm. The contribution of this study is registration of patient's MR image onto the Montreal Neurological Institute (MNI) image space by using automatically detected reference points. © 2015 IEEE
On the use of Spaceborne Remote Sensing for Archaeology: A case study on early iron production sites at the Jordan Valley
No full textThe purpose of this research was to investigate the surroundings of the Jordan Valley in Jordan with a large variety of spaceborne remote sensing data to examine the potential of this technique for the application of archaeology in general. The Jordan Valley is a region where many archaeological remains have been discovered, such as ancient settlements, old irrigation systems, and remains of early iron production. The used data sources includes multispectral (ASTER), hyperspectral (Hyperion), high-resolution (Quickbird), and radar data (ERS, Envisat and SIR-C). ASTER and Hyperion data are used to investigate the mineralogical content of the soil, whereas pan-sharpened Quickbird imagery is used to reveal the smallest structures in the landscape. Spectral field measurements are carried out as well for collecting groundtruth information. Radar (SAR) is used to map the terrain texture. Spaceborne remote sensing appears to be capable to map the known archaeological sites, showing its potential for the use in unexplored areas. However, the Jordan Valley itself is an area that is well known, and most archaeologically interesting features visible at the surface there are already documented, also detailed geological maps are available. No new discoveries therefore have been made.Aerospace Engineerin

No full textIntroduction: Tedizolid phosphate (TR-701) is a new oxazolidinone prodrug that is transformed in the serum into the active drug tedizolid (TR-700). Tedizolid acts by inhibiting protein synthesis and has broad activity against Gram-positive pathogens, including strains that are resistant to linezolid. Areas covered: This review summarizes the currently available data on this new antimicrobial agent. In vitro activity, pharmacokinetics-pharmacodynamics, clinical efficacy and safety are all addressed. Expert opinion: Tedizolid will provide a useful addition to the antimicrobial armamentarium, particularly in complicated skin and skin structure infections, due to its high oral bioavailability and once-daily dosing. The results of future studies will serve to better position tedizolid among the newly approved agents for infections caused by Gram-positive organisms. © 2012 Informa UK, Ltd.[Anonymous], 2001, AM J INFECT CONTROL, V29, P404; Betriu C, 2010, ANTIMICROB AGENTS CH, V54, P2212, DOI 10.1128-AAC.01653-09; Bien P., 2010, 50 INT C ANT AG CHEM; Brown SD, 2010, ANTIMICROB AGENTS CH, V54, P2063, DOI 10.1128-AAC.01569-09; Chang S, 2003, NEW ENGL J MED, V348, P1342, DOI 10.1056-NEJMoa025025; Colak D, 2002, J ANTIMICROB CHEMOTH, V50, P397, DOI 10.1093-jac-dkf134; Colca JR, 2003, J BIOL CHEM, V278, P21972, DOI 10.1074-jbc.M302109200; Dreskin H, 2011, 51 INT C ANT AG CHEM; Falagas ME, 2006, J ANTIMICROB CHEMOTH, V58, P273, DOI 10.1093-jac-dkl219; Fluit AC, 2001, J CLIN MICROBIOL, V39, P3727, DOI 10.1128-JCM.39.10.3727-3732.2001; Fridkin SK, 2005, NEW ENGL J MED, V352, P1436, DOI 10.1056-NEJMoa043252; Gould IM, 2008, INT J ANTIMICROB AG, V31, P1, DOI 10.1016-S0924-8579(08)70002-5; Hiramatsu K, 1997, J ANTIMICROB CHEMOTH, V40, P135, DOI 10.1093-jac-40.1.135; Housman ST, 2011, 51 INT C ANT AG CHEM; Hsueh PR, 1999, INFECT CONT HOSP EP, V20, P828, DOI 10.1086-501592; Im WB, 2011, EUR J MED CHEM, V46, P1027, DOI 10.1016-j.ejmech.2011.01.014; Jacobson LM, 2009, PEDIATR INFECT DIS J, V28, P445, DOI 10.1097-INF.0b013e3181927891; Jones RN, 2009, J ANTIMICROB CHEMOTH, V63, P716, DOI 10.1093-jac-dkp021; Keel RA, 2011, 51 INT C ANT AG CHEM; Kirst HA, 1998, ANTIMICROB AGENTS CH, V42, P1303; Leach KL, 2007, MOL CELL, V26, P393, DOI 10.1016-j.molcel.2007.04.005; LECLERCQ R, 1988, NEW ENGL J MED, V319, P157, DOI 10.1056-NEJM198807213190307; Lemaire S, 2009, J ANTIMICROB CHEMOTH, V64, P1035, DOI 10.1093-jac-dkp267; Livermore DM, 2009, J ANTIMICROB CHEMOTH, V63, P713, DOI 10.1093-jac-dkp002; Locke JB, 2009, ANTIMICROB AGENTS CH, V53, P5265, DOI 10.1128-AAC.00871-09; Louie A, 2011, ANTIMICROB AGENTS CH, V55, P3453, DOI 10.1128-AAC.01565-10; Mangili A, 2005, CLIN INFECT DIS, V40, P1058, DOI 10.1086-428616; Moellering RC, 2003, ANN INTERN MED, V138, P135; Moise PA, 2000, INT J ANTIMICROB AG, V16, pS31; Munoz KA, 2011, 21 EUR C CLIN MICR I; Prasad JV, 2007, CURR OPIN MICROBIOL, V10, P454, DOI 10.1016-j.mib.2007.08.001; Prokocimer P, 2008, 48 INT C ANT AG CHEM; Prokocimer P, 2011, ANTIMICROB AGENTS CH, V55, P583, DOI 10.1128-AAC.00076-10; Ramsey AM, 2009, INFECT CONT HOSP EP, V30, P184, DOI 10.1086-593956; Rodriguez-Avial I, 2012, J ANTIMICROB CHEMOTH, V67, P167, DOI 10.1093-jac-dkr403; Sakoulas G, 2004, J CLIN MICROBIOL, V42, P2398, DOI 10.1128-JCM.42.6.2398-2402.2004; Garcia MS, 2010, JAMA-J AM MED ASSOC, V303, P2260, DOI 10.1001-jama.2010.757; Schaadt R, 2009, ANTIMICROB AGENTS CH, V53, P3236, DOI 10.1128-AAC.00228-09; Shaw KJ, 2008, ANTIMICROB AGENTS CH, V52, P4442, DOI 10.1128-AAC.00859-08; SMALL PM, 1990, ANTIMICROB AGENTS CH, V34, P1227; UTTLEY AHC, 1989, EPIDEMIOL INFECT, V103, P173; van Hal SJ, 2011, EUR J CLIN MICROBIOL, V30, P603, DOI 10.1007-s10096-010-1128-3; VOSS A, 1994, EUR J CLIN MICROBIOL, V13, P50, DOI 10.1007-BF02026127; Woods CW, 2004, CLIN INFECT DIS, V38, P1188, DOI 10.1086-383027; Yamaki J, 2011, ANTIMICROB AGENTS CH, V55, P4432, DOI 10.1128-AAC.00122-11; Yum JH, 2010, ANTIMICROB AGENTS CH, V54, P5381, DOI 10.1128-AAC.00728-10; Zetola N, 2005, LANCET INFECT DIS, V5, P275, DOI 10.1016-S1473-3099(05)70112-214171
Studying Co-evolution of Production and Test Code Using Association Rule Mining
No full textUnit testing is generally accepted as an aid to produce high quality code, and can provide quick feedback to developers on the quality of the software. To have a high quality and well maintained test suite requires the production and test code to synchronously co-evolve, as added or changed production code should be tested as soon as possible. Traditionally the quality of a test suite is measured using code coverage, but this measurement does not provide insight in how tests are used by developers. In this thesis we explore a new approach to analyse how tests in a system are used based on association rules mined from the system’s change history. The approach is based on the reasoning that an association rule between two entities, possibly of a different type, is a measure for the co-use of the entities. Case studies show that analysing all the resulting rules allows us to uncover the distribution of programmer effort over pure coding, pure testing, or a more test-driven practice. Another application of our approach is that we can express the number of tests that are truly co-evolving with their associated production class.Software EngineeringSoftware TechnologyElectrical Engineering, Mathematics and Computer Scienc
Quaternion PCA and sparse PCA for shape variability
No full textPrincipal component analysis (PCA) is commonly used in the fields of computer graphics and geometry processing for constructing subspaces that represent the variability present in a dataset. Examples of such datasets are configurations of a non-rigid object, poses of a deformable character or snapshots from a simulation. By applying PCA to the dataset, one can generate a lower-dimensional space in which the data samples can be approximated well. Similar to PCA, one can also apply a sparse PCA technique to the geometric data. These methods aim to find components that do not only describe the deformations present in the data well, but are also sparse and localized.One of the problems related to PCA and sparse PCA is that they do not take the correlation between the x, y and z coordinates of each vertex into account when constructing the subspace. Furthermore, the methods are not invariant to rigid motion (rotations and translations) of the data samples, which means that rigid registration has to often be applied to the samples as a preprocessing step. Ideally, we would like to construct a subspace that is invariant to these rigid motions.This project investigates whether quaternions can be used to solve these problems. By describing each vertex as a pure quaternion, we show how quaternion PCA can be applied to geometric data and introduce a quaternion method of snapshots for improved computational efficiency. Additionally, we derive multiple quaternion sparse PCA techniques, which are inspired by the Sparse Localized Deformation Components (SPLOCS) method. Experimental results show that the quaternion PCA and sparse PCA methods are able to describe a richer space of deformations using fewer components. Furthermore, we show that quaternion PCA leads to improved rigid motion invariance.Computer Scienc
