The development and implementation of a performance management system: a case study

Whittington-Jones, Alexandra January 2005 (has links)
After a review of the literature relevant to performance management systems both over time and across different types of organizations, this thesis confines its research to a case study of the development and implementation of a performance management system in a non-governmental organization (NGO), the Public Service Accountability Monitor (PSAM). Collation of the relevant data is followed by a discussion of the development and implementation of the performance management system at the PSAM over a 5-year period from 1 June 1999 to 31 May 2004. This is considered in terms of the PSAM’s achievement of commitments to Funders and the concurrent development of the performance management system. Next an analysis of major themes that emerged from the research, in terms of important items for consideration in the development and implementation of a performance management system in an NGO, and areas for possible future improvements to the system is presented. After analyzing the relevant information, it became apparent that the performance management system has no direct bearing on the ability of the PSAM to achieve its stated commitment to Funders. However, these short-term focused expectations of the performance management system are outweighed by the positive contributions that have been made by its introduction, specifically in the area of training and development. This important aspect of capacity building and staff empowerment speaks to the long term sustainability of the organization. Although the PSAM’s performance management system undergoes continual improvement, significant inroads have been made into providing a sensible, clear and dynamic solution to the problem of rewarding efficient and effective performance. The PSAM has indeed benefited from the introduction of the performance management system in a number of ways. It is evident that these benefits could be applicable to other NGOs.

Smart coffee maker / Smart kaffebryggare

Ni, Houbo January 2017 (has links)
Nowadays, more and more people drink coffee not only from Starbucks or other shops, but also brew coffee from coffee maker which with proper sizes which they can be put in the resting room of companies or homes. The products of coffee maker polarize in the market. Some of them have powerful functions and nice tastes with high prices. The others are simple, cheap but losing enjoyment of drinking coffee and people need to keep an eye on status of coffee maker. Most of people prefer the cheaper type. But more functions will take more convenience. Actually users can have them both. In this thesis, I design some functions based on the cheap type of coffee maker which will make drinking coffee more convenient and enjoyable. I use Arduino Uno as my control system, cooperating with sensors and special circuits. My system monitor working time of coffee maker, temperature of coffee and water level of both coffee pot and tank in the coffee maker. Then users can receive these values from their cell phone and doing remote control. Meanwhile considering about prices, I choose the most suitable sensors for measurement. I also do some jobs for saving energy and safe. The system locks or turns off the switch automatically for them. At last, all the sensors, wires and control chip are put in good positions in the maker.

Zivčák, Jan January 2011 (has links)
With the development of posibilities of image processing, stereoscopy, prices of web cameras and power of computers an opportunity to multiply an experience with working with 3D programs showed. From the picture from webcamera an estimation of a pose of user's head can be made. According to this pose a view on 3D scene can be changed. Then, when user moves his head, he will have a feeling as if monitor was a window through which one can see the scene behind. With the system which is the result of this project it will be possible to easily and cheaply add this kind of behaviour to any 3D application.

Les centres de ressources en langues en milieu universitaire français : quelles ressources et quels dispositifs pour favoriser les auto-apprentissages ? / Language Resource Centers in French universities : what resources and what mechanisms to promote self-learning ?

Hernandez Freites, Elizabeth 02 December 2016 (has links)
Dans les CRL en milieu universitaire français des moniteurs orientent leurs semblables à l’apprentissage en autonomie des langues. Ces moniteurs sont évalués lors d’un entretien, afin de remplir diverses fonctions, au sein d’une structure corrélativement récente où, face au public la mise à disposition des ressources matérielles, technologiques et humaines se réalise.Cependant, la responsabilité qui leur est confiée découle de types distincts d’interventions qui évoluent au-delà de la fonction du monitorat, plus précisément liés à la gestion et l’animation du centre. Il s’agit, dans certains cas, d’exercer une médiation de tutelle pour l’autonomisation des apprenants. Des compétences très précises unies à l'ingérence humaine puis à la gestion des ressources matérielles s’impliquent par ce profil.Malgré cette polyvalence des fonctions, les moniteurs ne reçoivent pas de formation spécifique pour exercer l’accompagnement en langue. Il en découle une proposition de formation de notre part qui mêle une analyse sur les profils, les compétences que le tuteur doit détenir pour exercer le tutorat. / In the Language Resource Labs of the French university system, monitors direct their fellows in the independent learning of languages. These monitors are assessed during an interview in order to fulfill diverse tasks, within a correlative recent structure where, the provision to the general public of the equipment as well as the technological and human resources come true. However, the responsibility which is trusted to them stems from different types of interventions which evolve beyond the function of instructing, but more precisely bound to the management and the organization of the Lab; It is a matter, in certain cases of practicing a mediation of supervision of the self-learning process of the learners. Very specific skills, along with human intervention, then the management of material resources are involved in this job profile. In spite of this functional flexibility, monitors do not receive any particular training in order to exercise this language learning support. As a result, we propose a training, which analyzes the job profile as well as the skills that the instructor must have in order to practice the instruction.

Zdravý životní styl u žáků druhého stupně vybrané pražské základní školy / Healthy lifestyle of pupils of the second grade of selected Prague primary school

Rašovský, Matěj January 2021 (has links)
This diploma thesis Healthy lifestyle of pupils of the second grade of selected Prague primary school was prepared with the aim of finding out the healthy lifestyle of the pupils of the given group that is, pupils of the second grade of the Prague school. The standard CINDI Health Monitor method was used for this finding, thanks to which it is possible to compare healthy people's lifestyles across age groups. This method includes a standard set of questions to which probands answer dichotomously or yes-no. Our research has been supplemented by questions specific to our age group. These questions were evaluated by the percentage of positive answers and compared with previous surveys across age groups. Specifically with a group of students and adults over the age of 25. In terms of statistics, a correlate was also used, which better captured the relationship between the given age groups. Another goal of this work was to establish recommendations for the recovery of the health style of students who were the subject of this work, based on the intersection of the results with theoretical background. The selected group of pupils has a good health style, which may be due to the location of the school and also its culture, as there are many sports students. The main recommendation for pupils is to limit...

Cross section measurements on 61Cu for proton beam monitoring above 20 MeV

Kuhn, S., Buchholz, M., Wels, T., Breunig, K., Scholten, B., Spahn, I., Coenen, H. H. January 2015 (has links)
Introduction All experimental studies involving charged particle induced nuclear reactions require a precise knowledge of monitor reactions. A number of well described proton induced monitor reactions exist in the lower energy range [1], which is covered by most medical cyclotrons. Concerning proton energies above 20 MeV, however, the accuracy of the monitor reactions declines as cross section data becomes scarcer. Furthermore, the growing interest in precise determination of projectile energies by comparing of ratios of monitor reaction cross sections demands new measurements and evaluations of known data for high threshold monitor radionuclides. In this work cross section measurements on the formation of 61Cu were done and energy de-pendent radionuclide ratios were calculated. Material and Methods For investigation of the natCu(p,x)61Cu reaction copper foils of natural isotopic composition (Goodfellow Ltd.) were irradiated. The targets were of 10 and 20 μm thickness, having a diameter of 15 mm. Proton bombardments up to 45 MeV incident energy were done in the stacked-foil arrangement at the accelerator JULIC of the Nuclear Physics Institute (IKP) of the Forschungszentrum Jülich. In addition to an internal irradiation possibility the cyclotron is equipped with an external target station which was used for most experiments. It can adapt standard and slanting solid target holders and is equipped with a water cooled four sector collimator and additional helium cooling of the entry foil. Several irradiations were executed. In each stack, besides copper samples, aluminium absorbers and additional nickel monitor foils were also placed, the latter for the determination of the respective beam current. The produced radioactivity of 61Cu was analysed non-destructively using HPGe γ-ray detectors (EG&G Ortec). Results and Conclusion Reaction cross sections of the natCu(p,x)61Cu process up to 45 MeV were measured and com-pared with existing data from the literature (FIG. 2). Except for the data of Williams et al. our results are in good agreement, showing a maxi-mum of about 165 mbarn at 37.5 MeV proton energy. The overall uncertainty of the new cross section data is between 8 and 10 %. In FIG. 3, the excitation functions of the relevant monitor reactions on Cu are shown. In combination with the excitation function of the natCu(p,xn)62Zn reaction, isotope ratios were calculated which can be used for determination of the proton energy within a target stack in the energy range of 22–40 MeV as described by Piel et al. [3]. FIGURE 4 shows the cross section ratio in dependence of the proton energy. Above this energy, 65Zn could be used to generate isotope ratios for energy determination, although the long half-life (T½ = 244.3 d) of that radionuclide may be a problem. Additional cross section measurements are planned in order to further strengthen the data base of this potential monitor reaction. The results of this work shall be evaluated in the framework of an ongoing Coordinated Research Project of the IAEA.

Unter vier Augen – Erkenntnisse aus einer Eyetracking-Studie zum IÖR-Monitor

Eichler, Lisa 05 October 2020 (has links)
Der IÖR-Monitor stellt für das Leibniz-Institut für ökologische Raumentwicklung (IÖR) die zentrale Plattform zur Publikation von Geoinformationen für die Bundesrepublik Deutschland dar. Die Anforderungen an die Nutzerfreundlichkeit (Usability) des IÖR-Monitors erhöhen sich mit der Vielzahl und Heterogenität der Nutzer dieser Anwendungen, wie beispielsweise GIS-Experten oder politischen Entscheidern. Dabei stellt eine benutzerfreundliche und intuitiv bedienbare Oberfläche eine wesentliche Grundlage für die Recherche und Analyse der enthaltenen thematischen Geoinformationen dar. In einer Nutzerstudie wurde die Usability des IÖR-Monitors eingehend untersucht. Mit einer Methode zur Blickverfolgung (Eyetracking) konnten die Blicke der Probanden bei der Arbeit mit dem Monitor aufgezeichnet und analysiert werden. Zusammen mit den Ergebnissen der begleitenden Befragung, in denen subjektive Eindrücke der Teilnehmer erfasst wurden, ließen sich an die Usability des IÖR-Monitors neben derer Wahrnehmung auch weitere Anforderungen ermitteln. So zeigten sich neben den Stärken der Anwendung auch kleinere Schwächen.

Automatic event detection oncontinuous glucose datausing neural networks / Automatisk eventdetektion på kontinuerligglukosdata med användet av neurala nätverk

Borghäll, David January 2023 (has links)
Automatically detecting events for people with diabetes mellitus using continuousglucose monitors is an important step in allowing insulin pumps to automaticallycorrect the blood glucose levels and for a more hands-off approach to thedisease. The automatic detection of events could also aid physicians whenassisting their patients when referring to their continuous glucose monitordata. A range of different deep learning algorithms has been applied forpredictions of different events for continuous glucose monitor data, such asthe onset for hyperglycemia, hypoglycemia or mealtime events. This thesisfocused on constructing sequences labelled from an unbalanced and assumedmisslabelled dataset to classify them as such using four different deep learningnetworks using convoluted neural networks and recurrent neural networks.Manual correction of the dataset allowed for only clear events starting witha high positive gradient to be labelled as positive. The classification wasperformed on exact timepoints and in time windows to allow the classificationto to be done around the beginning of an event instead of the exact timepoint.The results from using the unbalanced and assumed misslabelled datasetshowed the networks performing similarly, with high Recall and Precisionbelow 0.5, thus not found to be of use in a for automatic event detection.Further testing by using another dataset or further configurations is neededto clarify the capabilities of automatically detecting events. DDAnalytics willnot use any of the developed networks in any of their products. / Automatisk detection av event för personer med diabetes från deras kontinuerligaglukosmätare är ett viktigt steg för att låta insulinpumpar automatiskt korrigeraglukosnivåer och möjliggöra en mindre självreglering av personens diabetes.Denna automatiska detektion skulle även kunna hjälpa läkare vid samtalmed patienter och deras data från kontinuerliga glukosmätarna. En mängd avolika djupinlärningsalgoritmer har använts för förutsägelser av olika event förkontinuerlig glukosmätardata, som början av hyperglykemier, hypoglykemiereller måltider. Detta examensarbete fokuserar på skapandet av sekvenserfrån ett obalanserat och antaget inte helt korrekt markerade event i dataset,för att kunna klassificera dessa event med fyra olika djupinlärningsnätverk.Dessa nätverk bygger på konvolution och rekursiva neurala nätverk. Manuellkorrektion av datasetet möjliggjorde så att endast tydliga event som börjar meden kraftig positiv ökning av gradienten var markerade som positiva event.Klassificeringen genomfördes på både exakta tidssteg och i tidsfönster såatt början av event kunde detekteras snarare än bara det exakta tidssteget.Resultaten genom användandet av detta tidigare nämnda dataset visade liknanderesultat för samtliga nätverk, med hög Återkallelse och Precision under 0.5.Dessa resultat ledde till att nätverken inte kan antas kunna utföra automatiskevent detektion, och skulle behöva ytterligare testning på ett annat dataset medmer korrekta markerade event eller ytterligare konfigureringar på nätverken föratt verifiera dessas möjligheter att automatiskt klassificera event i kontinuerligglukosdata. DDanalytics kommer inte använda något av dessa framtagnanätverk i några av deras produkter.

Panoramic Video for Efficient Ground Surveillance from Small Unmanned Air Vehicles

Jackson, Joseph Aaron 16 April 2007 (has links) (PDF)
As unmanned air vehicle (UAV) utilization increases in Wilderness Search and Rescue (WiSAR) efforts, onboard sensors yielding more information will be desired. UAVs can assist WiSAR efforts by accelerating the ground search process through returning quality aerial footage of the terrain. Additionally, tracking the progress of a search by populating a digital map with video resolution data increases confidence that a comprehensive search of the region has been made. This thesis presents methods for acquiring video from multiple video sensors and fusing them into a single rendered video stream as a Virtual Gimbal. The panoramic video stream is the first of its kind to be constructed from video transmissions from a small UAV, and the first known video panorama to be used to quickly survey a region within a WiSAR context. The Virtual Gimbal comprises two video transmissions from a three camera array mounted in a downward-looking configuration on a UAV. This video stream has been shown to decrease the amount of time required to thoroughly survey a region by more than 40 percent.
