Enterprise storage systems are generally shared by multiple servers in a SAN environment. Our experiments as well as industry reports have shown that disk arrays show poor performance when multiple servers share one RAID due to resource contention as well as frequent disk head movements. We have studied IO performance characteristics of several shared storage settings of practical business operations. To avoid the IO contention, we propose a new dynamic data relocation technique on shared RAID storages, referred to as DROP, Dynamic data Relocation to Optimize Performance. DROP allocates/manages a group of cache data areas and relocates/drops the portion of hot data at a predefined sub array that is a physical partition on the top of the entire shared array. By analyzing profiling data to make each cache area owned by one server, we are able to determine optimal data relocation and partition of disks in the RAID to maximize large sequential block accesses on individual disks and at the same time maximize parallel accesses across disks in the array. As a result, DROP minimizes disk head movements in the array at run time giving rise to high IO performance. A prototype DROP has been implemented as a software module at the storage target controller. Extensive experiments have been carried out using real world IO workloads to evaluate the performance of the DROP implementation. Experimental results have shown that DROP improves shared IO performance greatly. The performance improvements in terms of average IO response time range from 20% to a factor 2.5 at no additional hardware cost.

Screening programs exist for diseases that are common and often asymptomatic in the earlier stages, and if they are detected in the initial phase, the chances of a cure are notably higher. Therefore, the goal of health systems is to ensure 100% coverage in the implementation of screening. Unfortunately, the real coverage is far smaller and often below 50%, hence the issue of efficient screening is very important. This paper presents software support that is implemented in three ways and aims at more efficient implementation of screening programs. The production of a software module for the registration of patients for screening programs, significantly facilitates the traditional access to this data and enables the higher coverage of the target population. Another way to support screening is provided by business intelligence tools, by creating a hypercube over existing data. It is also possible to use artificial intelligence to improve the efficiency of screening programs.

The simulation of the dynamics of the blood flow in the venous system of the lower limb is an important tool for supporting clinical research and for suggesting possible treatments for many diseases, e.g. for enhancing the surgical treatment of Chronic Venous Insufficiency (CVI). Nevertheless the accuracy of the simulation of the blood flow is strictly related to the morphological data characterizing the investigated venous system. Although some of these data can be extracted from the observation of the real blood flow of a patient, e.g. through the acquisition of a set of images, the extraction of such values is often performed in a manual way, so the need for the automatic induction of parameters arises. The paper presents a software module that allows the semiautomatic acquisition of the morphological data of the venous system of a patient. The tool, developed as a plugin of the ImageJ imaging platform, receives in input a DICOM file containing the Computerized Tomography (CT) of the vessels network of the lower limb, and produces in a semi-automatic way a weighted graph of the network. This model can be used as the input for a subsequent simulation of the system.

A number of V&V datasets are publicly available. These datasets have software measurements and defectiveness information regarding the software modules. To facilitate V&V, numerous defect prediction studies have used these datasets and have detected defective modules effectively. software developers and managers can benefit from the existing studies to avoid analogous defects and mistakes if they are able to find similarity between their software and the software represented by the public datasets. This paper identifies the similar datasets by comparing association patterns in the datasets. The proposed approach finds association rules from each dataset and identifies the overlapping rules from the 100 strongest rules from each of the two datasets being compared. Afterwards, average support and average confidence of the overlap is calculated to determine the strength of the similarity between the datasets. This study compares eight public datasets and results show that KC2 and PC2 have the highest similarity 83% with 97% support and 100% confidence. Datasets with similar attributes and almost same number of attributes have shown higher similarity than the other datasets.

The work presents general approaches to the construction of the software and hardware stable complex. The complex is capable to detect textural annual rings of round timber with subsequent the object internal macrostructure reconstruction based on the data obtained. The complex constructions are based on algorithms for processing binary and grayscale images using algorithms for identifying informative features and applying the Hough transform. The complex using is aimed to provide tools for simplifying the round timber cutting process and visualizing of its cutting results in the required form. The work reflects the results of creating the round timber macrostructure reconstruction and visualization model with the functions variety for changing the shape and size of the object. The possibility of constructing sections both in 2D and in 3D is achieved also it is possible to obtain the surfaces projections in the plane of sections. Such results allow visually evaluate the round timber texture pattern in a specific coordinate plane in the of round timber volume. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Heat Integration (HI) with heat exchangers requires intimate knowledge and intensive calculations to set energy-saving targets to achieve the goal of efficient energy utilisation. The Shell and Tube Heat Exchanger (STHX) Design software module, or SPIL-HX package developed by the SPIL team, offers features that support engineers to design and rate original STHXs, STHXs coupled with the shell-side enhancement technologies, i.e., with segmented baffles and with helical baffles. This software tool also provides design solutions for the Waste Gas Compact Thermal Oxidiser (WGCTO), identifying the unit design capable of simultaneous combustion and heat exchange for waste gases. SPIL-HX package is also capable of automatic Heat Exchanger Network (HEN) synthesis and retrofit. With the built-in algorithm, the software can provide the optimal solution for HI, which significantly reduces operating, capital, and design costs. A user-friendly interface facilitates the use of the developed software.(c) 2022 Elsevier Ltd. All rights reserved.

Incorporating Prerecorded Environmental Lifecycle Assessment modules in a Classroom Setting

Addition of sustainability-related material is becoming a point of emphasis in engineering education. Freely available modular lessons are one way to quickly effect this incorporation. This research examines the effectiveness of a class format using short prerecorded software modules on lifecycle assessment (LCA) in the classroom setting with associated discussion, primarily drawing from student perspectives in a graduate-level LCA course at Washington State University. Survey results indicated that students generally agreed that the in-class module-discussion format was an effective teaching method. Advantages included that the format was organized and complete, but still concise, allowed for review of material outside of class, and that discussion components furthered understanding and stimulated further thought about the concepts. Key disadvantages included that the modules can get boring, were sometimes too fast-paced, and that questions usually were held until the end of the presentation. Students were happy with the length of modules (about 20min each), but many expressed a desire for additional discussion time. Recommendations for future versions of the course include taking additional breaks during modules for discussion, encouraging students to ask questions at any time, and suggesting that some students print slides to stay engaged with note taking. In the future it is anticipated that these types of narrated modules will make it easier for other instructors to provide more sustainability education in their classrooms.
