SCADA Test Bed - Water Tank System

A SCADA, or Supervisory Control And Data Acquisition, system is a computer-controlled system that monitors and controls industrial processes remotely. Electric grids, water supplies, and pipelines are all significant SCADA systems. These systems can be controlled and monitored remotely and are typically composed of multiple programmable logic controllers (PLCs). However, SCADA systems are inherently vulnerable to cyber attacks. During the previous academic year, an electrical engineering senior project team was assigned the task of designing and constructing a SCADA test bed for WKU’s Engineering-Manufacturing-Commercialization Center (EMCC). The test bed was to have three systems simulating SCADA systems: a traffic light system, a water tank system, and a power grid system. Because there were three systems desired, the three-person project was separated into three parts. Each person was charged with the hardware design, programming, and implementation of a system. The focus of this research project was the water tank system. This paper details the hardware and software design process that was eventually built and implemented and discusses the problems that were encountered and how they were solved

Diagnostic Implications from Clinical Assessment of Movement Pathology Across Contexts Using the Movement Psychodiagnostic Inventory: A Comparison Study

The Movement Psychodiagnostic Inventory (MPI) is an assessment tool, that uses movement observation for the purpose of diagnosing individuals with mental illnesses. The MPI requires extensive training as well as access to a videotape of a seated interview and several hours to carefully observe an individual in conversation. In 2007, a short-form version of the MPI was created for the clinical use of the instrument in dance/movement therapy (DMT) assessment. To date, no known use of this novel instrument has been published. In this pilot study, one rater with extensive experience with the MPI used both forms of the MPI to assess videotaped sessions one individual in both a DMT assessment session as well as a seated interview during his stay in an inpatient psychiatric facility. Both instruments were used in each context, and the researcher compared the data across all contexts. In this study, the results indicated that each assessment instrument when used in its intended context uncovered similar movement patterns in the same individual, suggesting that the novel instrument could be applicable in a DMT setting. Because this study had an N of 1, the results are not generalizable nor did the study test the validity of the instrument. The findings of this pilot study, however, suggest that further research should be conducted by multiple raters in several different contexts using multiple participants. In addition to further research, a publication of guidelines for use and available trainings would make the short-form MPI a valuable assessment tool for dance/movement therapists working in a clinical setting with people with mental illness.M.A., Dance/Movement Therapy and Counseling -- Drexel University, 201

From Theory to Action: Developing and Evaluating Learning Analyticsfor Learning Design

Producción CientíficaThe effectiveness of using learning analytics for learning design primarily depends upon two concepts: grounding and alignment. This is the primary conjecture for the study described in this paper. In our design-based research study, we design, test, and evaluate teacher-facing learning analytics for an online inquiry science unit on global climate change. We design our learning analytics in accordance with a socioconstructivism-based pedagogical framework, called Knowledge Integration, and the principles of learning analytics Implementation Design. Our methodology for the design process draws upon the principle of the Orchestrating for Learning Analytics framework to engage stakeholders (i.e. teachers, researchers, and developers). The resulting learning analytics were aligned to unit activities that engaged students in key aspects of the knowledge integration process. They provided teachers with actionable insight into their students' understanding at critical junctures in the learning process. We demonstrate the efficacy of the learning analytics in supporting the optimization of the unit's learning design. We conclude by synthesizing the principles that guided our design process into a framework for developing and evaluating learning analytics for learning design.Ministerio de Ciencia, Innovación y Universidades (Project TIN2017-85179-C3-2-R)Junta de Castilla y León (project VA257P18) by the European Commission under project grant 588438-EPP-1-2017-1-EL-EPPKA2-KA

Child Life Specialists’ Evaluation of Hospital Playroom Design: A Mixed Method Inquiry

This study uses the expertise of child life specialists to identify which elements support child life goals for hospitalized children. This study can be used to inform those interested in the optimal design of hospital playrooms. Ninety child life specialists were surveyed using a photograph methodology showing five actual child life playrooms from different hospitals. The participants were asked the following: rate each playroom on 14 dimensions; describe what was liked best about each playroom; and finally, rank order the playrooms based on their ability to support child life goals. Findings show that child life specialists were able to detect fine distinctions among hospital playrooms; thus, highlighting the important role that child life specialists can play in the design or modification of these spaces. Notably, using both Likert ratings and open-response questions, the value of biophilia in child life play spaces, specifically windows, light, and nature themes were revealed. In addition to biophilic attributes, the playrooms rated most favorably were those that contain pleasing color and décor and plenty of open space. Playrooms that promote sensory-motor and pretend play were also preferred

Trends in AIDS-defining and non-AIDS-defining malignancies among HIV-infected patients: 1989-2002

In a comparison of rates of acquired immunodeficiency syndrome (AIDS)-defining malignancies (ADMs) for 1989-1996 versus 1997-2002, we found a decrease in ADMs (rate ratio, 0.31; P\u3c.0001) and a significant increase in non-AIDS-defining malignancies (non-ADMs; rate ratio, 10.87; P\u3c.0002). The mean CD4 cell count was lower among patients with ADMs than among those with non-ADMs. A longer duration of survival during highly active antiretroviral therapy might explain the increasing incidence of non-ADMs

Nail abnormalities identified in an ageing study of 30 inbred mouse strains.

In a large-scale ageing study, 30 inbred mouse strains were systematically screened for histologic evidence of lesions in all organ systems. Ten strains were diagnosed with similar nail abnormalities. The highest frequency was noted in NON/ShiLtJ mice. Lesions identified fell into two main categories: acute to chronic penetration of the third phalangeal bone through the hyponychium with associated inflammation and bone remodelling or metaplasia of the nail matrix and nail bed associated with severe orthokeratotic hyperkeratosis replacing the nail plate. Penetration of the distal phalanx through the hyponychium appeared to be the initiating feature resulting in nail abnormalities. The accompanying acute to subacute inflammatory response was associated with osteolysis of the distal phalanx. Evaluation of young NON/ShiLtJ mice revealed that these lesions were not often found, or affected only one digit. The only other nail unit abnormality identified was sporadic subungual epidermoid inclusion cysts which closely resembled similar lesions in human patients. These abnormalities, being age-related developments, may have contributed to weight loss due to impacts upon feeding and should be a consideration for future research due to the potential to interact with other experimental factors in ageing studies using the affected strains of mice.American Hair Research Society Mentorship Grants (to SL and AM) Ellison Medical Foundation (to JPS) National Institutes of Health (AG025707, for the Shock Aging Center).

Search for the lepton-flavor-violating decays Bs0→e±μ∓ and B0→e±μ∓

A search for the lepton-flavor-violating decays Bs0→e±μ∓ and B0→e±μ∓ is performed with a data sample, corresponding to an integrated luminosity of 1.0  fb-1 of pp collisions at √s=7  TeV, collected by the LHCb experiment. The observed number of Bs0→e±μ∓ and B0→e±μ∓ candidates is consistent with background expectations. Upper limits on the branching fractions of both decays are determined to be B(Bs0→e±μ∓)101  TeV/c2 and MLQ(B0→e±μ∓)>126  TeV/c2 at 95% C.L., and are a factor of 2 higher than the previous bounds

Measurement of the ratio of branching fractions BR(B0 -> K*0 gamma)/BR(Bs0 -> phi gamma) and the direct CP asymmetry in B0 -> K*0 gamma

The ratio of branching fractions of the radiative B decays B0 -> K*0 gamma and Bs0 phi gamma has been measured using an integrated luminosity of 1.0 fb-1 of pp collision data collected by the LHCb experiment at a centre-of-mass energy of sqrt(s)=7 TeV. The value obtained is BR(B0 -> K*0 gamma)/BR(Bs0 -> phi gamma) = 1.23 +/- 0.06(stat.) +/- 0.04(syst.) +/- 0.10(fs/fd), where the first uncertainty is statistical, the second is the experimental systematic uncertainty and the third is associated with the ratio of fragmentation fractions fs/fd. Using the world average value for BR(B0 -> K*0 gamma), the branching fraction BR(Bs0 -> phi gamma) is measured to be (3.5 +/- 0.4) x 10^{-5}. The direct CP asymmetry in B0 -> K*0 gamma decays has also been measured with the same data and found to be A(CP)(B0 -> K*0 gamma) = (0.8 +/- 1.7(stat.) +/- 0.9(syst.))%. Both measurements are the most precise to date and are in agreement with the previous experimental results and theoretical expectations.Comment: 21 pages, 3 figues, 4 table

Measurement of B meson production cross-sections in proton-proton collisions at √s= 7 TeV

The production cross-sections of B mesons are measured in pp collisions at a centre-of-mass energy of 7 TeV using data collected with the LHCb detector corresponding to a integrated luminosity of 0.36fb−1. The B+, B0 and B0s mesons are reconstructed in the exclusive decays B+→J/ψK+, B0→J/ψK∗0 and B0s→J/ψϕ, with J/ψ→μ+μ−, K∗0→K+π− and ϕ→K+K−. The differential cross-sections are measured as functions of B meson transverse momentum pT and rapidity y, in the range 0 < pT<40GeV/c2 and 2.0<y<4.5. The integrated cross-sections in the same pT and y ranges, including charge-conjugate states, are measured to be σ(pp→B++X)=38.9±0.3(stat.)±2.5(syst.)±1.3(norm.)μb, σ(pp→B0+X)=38.1±0.6(stat.)±3.7(syst.)±4.7(norm.)μb, σ(pp→B0s+X)=10.5±0.2(stat.)±0.8(syst.)±1.0(norm.)μb, where the third uncertainty arises from the pre-existing branching fraction measurements
