This report describes the design and construction of a tilting platform for sorting household waste, limited to plastic, glass, and metal. The platform utilizes a capacitive sensor to identify if an object is placed on the platform, an inductive sensor to detect metal, and a load cell to differentiate between plastic and glass based on their weight difference. The load cell was found to be inaccurate due to sensitivity to physical changes in the environment and sensor placement, leading to inaccurate weight measurements. Relocating the sensors away from the load cell is recommended to improve accuracy. The platform tilts using to two servomotors, which makes the platform tilt in two degrees of freedom. This solution worked as thought out, except for the universal joint having poor quality, resulting in a wobbly motion. / Denna rapport beskriver designen och konstruktionen av en vippande plattform för sortering av hushållsavfall begränsat till plast, glas och metall. Plattformen använder en kapacitiv sensor för att identifiera om ett föremål placeras på den, en induktiv sensor för att detektera metall och en lastcell för att skilja mellan plast och glas baserat på deras viktskillnad. Lastcellen visade sig vara opålitlig på grund av dess känslighet för fysiska förändringar i miljön och placeringen av sensorerna, vilket ledde till felaktiga viktmätningar. Det rekommenderas att flytta sensorerna bort från lastcellen för att förbättra noggrannheten. Den lutande funktionen drivs av två servomotorer som var funktionell men hade en ostadig rörelse på grund av dåliga universal joints.

Electric propulsion systems utilize electrical energy to produce thrust for spacecraft propulsion. These systems have multiple applications ranging from Earth orbit North-South station keeping to solar system exploratory missions such as NASA’s Discovery, New Frontiers, and Flagship class missions that focus on exploring scientifically interesting targets. In an electromagnetic thruster, a magnetic field interacting with current in an ionized gas (plasma) accelerates the propellant to produce thrust. Pulsed inductive thrusters rely on an electrodeless discharge where both the magnetic field in the plasma and the plasma current are induced by a time-varying current in an external circuit. The multi-dimensional acceleration model for a pulsed inductive plasma thruster consists of a set of circuit equations describing the electrical behavior of the thruster coupled to a one-dimensional momentum equation that allow for estimating thruster performance. Current models lack a method to account for the time-varying energy distribution in an inductive plasma accelerator.

Heart disease is one of the most prevalent diseases in the world. The survival chances for patients with ventricular fibrillation/ventricular tachycardia reduces significantly as time passes without treatment and even after getting timely treatment recurring episode are common. These patients can benefit from an Implantable Cardioverter Defibrillator (ICD) which can monitor heart rhythm and provide immediate treatment. Due to the ever changing physical conditions and disease progression, the ICD needs to collect diagnostic data as well as support programming by the physician. The ICD uses inductive telemetry and radio-frequency telemetry for the communication with the external devices such as a programmer or a monitor. Inductive telemetry uses less energy than RF telemetry but has a very short range of communication. In addition to inductive telemetry, the St. Jude Medical ICD supports 2.45 GHz band based asynchronized wakeup and 400 MHz MICS band based synchronized wakeup. The 2.45 GHz band based wakeup has limited wakeup range and the 400 MHz MICS based synchronized wakeup has limited availability for connection because it requires synchronization with the base station. The enhanced Medical Implant Communications Service (eMICS) algorithm is a firmware based algorithm which addresses the issues with other two wakeup schemes and provides fast, robust, and seamless wakeup. This thesis describes the design, implementation, and initial testing of eMICS algorithm on the Unity device platform in Technology Project Management (TPM) phase. The eMICS automated test tool developed at St. Jude Medical was used to test the eMICS algorithm under a controlled lab environment, typical home environment, typical hospital/clinic environment, and in the field. The project was successfully completed and transferred to Product Project Management (PPM) phase. However, the suggested duration of 60-90 seconds for sniff interval which will cause the least effect on the battery life was found unacceptable, and there is also a strong need for energy efficient hardware which draws minimal amount of current during each sniff. Therefore, St. Jude Medical is collaborating with the hardware vender to implement eMICS algorithm in the next version of hardware.

This study explored the relationships between roughly 330 participants' tolerance of ambiguity and their preference for either an inductive or deductive presentation of grammar by means of an online survey. Most participants were college students. Other variables examined included years of study, in-country experience, proficiency, age, year in school, and language of choice. A new instrument for measuring inductive vs. deductive preference was also created based on Cohen, Oxford, and Chi's (2001) Learning Style Survey (LSS). Results showed weak correlations between: tolerance of ambiguity and inductive preference (.25), tolerance of ambiguity and proficiency (.25), and inductive preference and proficiency (.20). Additional findings include: a correlation (.62) between proficiency and years of instruction received, a slight correlation (.22) between age and tolerance of ambiguity, no correlation between years of language instruction and tolerance of ambiguity, no correlation between studying abroad and ambiguity tolerance or inductive/deductive preference, and no correlation between age and inductive vs. deductive preference. Lastly, data was analyzed to determine whether language was a contributing factor or not, and only the participants learning Japanese were significantly different (p = .004), with a higher preference for inductive learning.

Yes / A dynamic response analysis model of a Class E2 converter for wireless power transfer applications is presented. The converter operates at 200 kHz and consists of an induction link with its primary coil driven by a class E inverter and the secondary coil with a voltage-driven class E synchronous rectifier. A seventh-order linear time invariant state-space model is used to obtain the eigenvalues of the system for the four modes resulting from the operation of the converter switches. A participation factor for the four modes is used to find the actual operating point dominant poles for the system response. A dynamic analysis is carried out to investigate the effect of changing the separation distance between the two coils, based on converter performance and the changes required of some circuit parameters to achieve optimum efficiency and stability. The results show good performance in terms of efficiency (90–98%) and maintenance of constant output voltage with dynamic change of capacitance in the inverter. An experiment with coils of the dimension of 53 × 43 × 6 mm3 operating at a resonance frequency of 200 kHz, was created to verify the proposed mathematical model and both were found to be in excellent agreement.

Bakgrund: Antalet patienter som behöver vård i hemmet ökar stadigt. För att vården ska ske personcentrat och patientsäkert, så behövs en god teamsamverkan mellan läkare och distriktssköterskor. Det är angeläget att undersöka hur denna teamsamverkan mellan distriktssköterskor och läkare fungerar för att kunna identifiera områden där förbättringar krävs. Syfte: Syftet var att beskriva distriktssköterskors erfarenheter av teamsamverkan med läkare i hemsjukvården. Metod: En kvalitativ intervjustudie genomfördes med induktiv ansats. Ändamålsenligt urval tillämpades och resulterade i 15 semistrukturerade intervjuer. Informanterna bestod av distriktssköterskor, grundutbildade sjuksköterskor och en specialistsjuksköterska inom vård av äldre från nio olika kommuner i södra Sverige. Samtliga informanter var kvinnor. Kvalitativ innehållsanalys användes för bearbetning av datamaterialet. Resultat: Tre kategorier framkommer i resultatet: Distriktssköterskors erfarenheter av läkares tillgänglighet i hemsjukvården, Respekt mellan distriktssköterskor och läkare i hemsjukvården samt Distriktssköterskors erfarenheter av hemsjukvårdens och vårdcentralens organisering. Kategorierna mynnade ut i ett gemensamt tema som lyder: Distriktssköterskor och läkare i hemsjukvården behöver varandra. Slutsats: Teamsamverkan mellan distriktssköterskor och läkare är nödvändigt i hemsjukvården. Samverkan brister mellan distriktssköterskor och läkare likväl mellan hemsjukvård och vårdcentral. Teamsamverkan mellan professioner och samverkan mellan hälsoorganisationer måste förbättras för att främja patienters hälsa. / Background: The number of patients being dependent on home care is constantly increasing. In order to provide patient-centered and safe health care, good team collaboration between general practitioners and district nurses must be established. It is important to investigate how this team collaboration is facilitated as this could provide better understanding of the topic which could pinpoint areas of improvement. Purpose: The purpose was to describe district nurses' experiences of team collaboration with general practitioners in home care. Method: A qualitative interview study was carried through with an inductive approach. Purposive sampling was applied and resulted in 15 semi-structured interviews. The informants consisted of district nurses, registered nurses and one specialist nurse of elderly care from nine different municipalities in south of Sweden. All informants were women. Qualitative content analysis was applied to process the gathered data. Results: The result is presented in three different categories: District nurses' experiences of general practitioners' accessibility in home care, Respect between district nurses and general practitioners in home care, District nurses' experiences of the organization of home care and health care centers. These categories resulted in a general theme described as: District nurses and general practitioners in home care need each other. Conclusions: Team collaboration between district nurses and general practitioners is vital within the home care sector. Collaboration between home care providers and health centers is also necessary for enabling this team collaboration. The result of this study shows that the team collaboration is lacking between district nurses and general practitioners as well as between home care providers and health centers. The team collaboration between both professions and health organizations must be improved in order to promote the health of all patients.

Despite the increased use of criminal profiling by law enforcement agencies, few studies examine factors impacting profile accuracy, and only one has evaluated profiler training. The present study examined the efficacy of profiler training on profile accuracy for sexual homicide offenders. Participants (N = 198) were randomly assigned to the training or control condition. Participants in the training condition learned inductive and deductive profiling techniques for sexual homicide offenders, whereas control participants learned about sexual violence prevention. Results indicated that participants’ self-reported use of combined profiling methods produced more accurate profiles. Differences between gender and training groups were also present. These findings suggest brief psychology-based training can be used to teach police officers and detectives to more accurately identify and apprehend criminals.
