Measurement of the magnetic field of small magnets with a smartphone: a very economical laboratory practice for introductory physics courses

In this work, we propose an inexpensive laboratory practice for an introductory physics course laboratory for any grade of science and engineering study. This practice was very well received by our students, where a smartphone (iOS, Android, or Windows) is used together with mini magnets (similar to those used on refrigerator doors), a 20 cm long school rule, a paper, and a free application (app) that needs to be downloaded and installed that measures magnetic fields using the smartphone's magnetic field sensor or magnetometer. The apps we have used are: Magnetometer (iOS), Magnetometer Metal Detector, and Physics Toolbox Magnetometer (Android). Nothing else is needed. Cost of this practice: free. The main purpose of the practice is that students determine the dependence of the component x of the magnetic field produced by different magnets (including ring magnets and sphere magnets). We obtained that the dependency of the magnetic field with the distance is of the form x-3, in total agreement with the theoretical analysis. The secondary objective is to apply the technique of least squares fit to obtain this exponent and the magnetic moment of the magnets, with the corresponding absolute error.

Retail centers for community : addressing both pedestrian and car traffic

The purpose of this thesis was to redesign a commercial center in Miami, Florida in a manner that incorporates the needs of pedestrians as well as the automobile. In my research, I studied projects that had been successful at integrating cars in retail design. I applied the strategies learned from this research to the design of a center that creates a positive interaction of pedestrian and car traffic, addressing the needs of the surrounding community. I designed a master plan that includes a mix of residential, retail, commercial and parking space. The parking is designed so that the retail center is not dominated by surface parking. Rather, the automobile is introduced into the different layers of the proposed buildings. The design focused on connecting pedestrian plazas and parking areas beneath them through the introduction of light and greenery. The findings show how a shopping center might transform the area around it by including spaces for residential, civic, cultural and social functions, as well as for the automotive infrastructure that make those functions possible.

UTFORMNING AV GÅNG-, CYKEL- OCH MOPED-NÄT ANPASSAT FÖR ELCYKEL

Purpose: An increase in the number of pedelecs on Swedish roads is according to studies soon reality. This creates a need to adapt the bmp-grid (bike-, moped- and pedestrian-grid) to pedelecs for them to experience good security, accessibility and comfort while using it. The guidelines Swedish municipalities follow are VGU(Design of Roads and Streets) and the GCM-manual(Bike-, moped-, and pedestrian-manual) which currently do not take society’s future increase of pedelecs into account. VGU and the GCM-manual are tools that are commonly used during planning and design of roads and streets. The aim of the thesis is to use current advice and recommendations on how to adapt the bmp-grid to the pedelec and with this complete current guidelines for bmp-infrastructure. Method: The document-analysis is made on current federal documents that have an impact on bmp-design. Scetch-suggestions were then developed from the author’s personal improvement suggestions and from advice and recommendations gathered during the document-analysis and the theoretical framework. Findings: It was discovered that if the bmp-grid’s design allow bikes traveling up to 30km/h and has a good standard for bicycles according to VGU, then the infrastructure generally fulfil the needs of the pedelec. Altough there are still areas in VGU that needs complements. This need to be done on the design-guidelines so they can aid the adaption of the infrastructure to the pedelec during the planning- and design process. Necessary steps according to the result is to give clearer notifications on bmp-design, issue guidelines for choosing DTS, motivate minimal widths on roads, categories bikers and pedestrians into separate groups, give out more detailed descriptions of when separation of bikers and pedestrians should be done and also to specify different types of bike-users. When taking needs and claim of the pedelec into consideration the result shows that: adaption of the whole bmp-grid to the pedelec is not possible, to simplify priorities the bmp-grid needs to be divided into different sections, space should be taken from the car-traffic, solutions with mixed-traffic and bike-fields for pedelecs can be used in low-speed areas, larger opportunities to connect towns to increase commuting with bicycles appeared with the pedelec. Implications: After examining current guidelines regarding the design of the bmp-grid and gathering opinions on this from interviews the conclusion is that several areas in VGU needs completion. The following are recommendations on how to take the pedelec into consideration during the design-process:• Connect towns and urban-areas with bmp-grids to make use of pedelecs capacity.• Where there is not enough space for both cars and separated pedelec- and bike lanes the speed for car-traffic can be lowered to 30km/h. This creates opportunities with mixed-traffic or bike-lanes.• The width of existing roads and streets are often greater than what’s described in VGU. They can be made smaller to free space on roads for bicycle-infrastructure.• To prioritize which parts of the bmp-grid that needs design to allow pedelecs the bmp-grid can be divided into main- and local grid. The main grid should be design with consideration to the needs and claim of the pedelecs. Limitations: The limitation of the study lies in that none of the interviews where done with employees in any of the bigger municipalities in Sweden. This gives the study a general application in small- to middle-sized cities but not in bigger cities.Keywords: elcykel, ebike, pedelec, utformning, cykel, infrastruktur, infrastructure, society, planering, utformning, säkerhet, fordonstyp

A qualitative impairment in face perception in Alzheimer’s disease : evidence from a reduced face inversion effect

Prevalent face recognition difficulties in Alzheimer’s disease (AD) have typically been attributed to the underlying episodic and semantic memory impairment. The aim of the current study was to determine if AD patients are also impaired at the perceptual level for faces, more specifically at extracting a visual representation of an individual face. To address this question, we investigated the matching of simultaneously presented individual faces and of other nonface familiar shapes (cars), at both upright and inverted orientation, in a group of mild AD patients and in a group of healthy older controls matched for age and education. AD patients showed a reduced inversion effect (i.e., larger performance for upright than inverted stimuli) for faces, but not for cars, both in terms of error rates and response times. While healthy participants showed a much larger decrease in performance for faces than for cars with inversion, the inversion effect did not differ significantly for faces and cars in AD. This abnormal inversion effect for faces was observed in a large subset of individual patients with AD. These results suggest that AD patients have deficits in higher-level visual processes, more specifically at perceiving individual faces, a function that relies on holistic representations specific to upright face stimuli. These deficits, combined with their memory impairment, may contribute to the difficulties in recognizing familiar people that are often reported in patients suffering from the disease and by their caregivers.

The wealth effects of commercial bank securities issuances announcement

Banks are often excluded in corporate finance research mainly because of the regulatory concerns. Compares to non-bank firms, banks are heavily regulated due to its special economic role of money and the uncertainty. Heavy regulation on banks could reduce the information asymmetry between the managers and investor by limiting the behaviour of banks at the time of the Seasoned Equity Offering (SEO), and by increasing the incentive for banks to avoid excessive risk-taking. Therefore, the market may be less likely to assume that bank issued securities signal information that the bank is overvalued compared to their non-bank counterparts. The objective of this thesis is therefore to examine commercial banks issued securities announcement effect. Three interrelated research questions are addressed in this thesis: 1) What is the difference in convertible bond announcement effect between banks and non-banks firm? 2) What is the difference in SEO announcement effect between banks and non-banks? 3) How do the stringency levels of bank regulation impact on the announcement effects of bank issued SEO? By using the U.S. convertible bond and SEO data from 1982 to 2012, I find that the bank issued a convertible bond and SEO announcement experience higher cumulative abnormal return than non-bank. This is consistent with the view that bank regulation reveals positive information about banks. Since banks are heavily regulated, the market is less likely to assume that the issuance of the convertible bond and SEO by banks signals information that is overvalued. These results are robust after controlling for a number of firm-, issue-, and market-specific characteristics. These results are robust by considering the different categories of non-bank industries by undertaking tests in relation to the differences in the CARS upon convertible bond/ SEO across industries, as well as the unbalanced sample between banks and non-banks by using the matched sample analysis. However, the relation between the stringency level of bank regulation and bank issued securities announcement effect may be nonlinear. As hypothesised, I find that bank regulation has an inverted U-shaped relation with the announcement effect of bank SEO by using the SEO data across 21 countries from 2001 to 2012. Under a less bank regulation environment, the market reacts more positively to the bank SEO announcement for an increase in the level of bank regulation. However, the bank SEO announcement effects become more negative if the bank regulation becomes too stringent. This inverted U-shaped relationship is robust after I use the exogenous cross-country, cross-year variation in the timing of the Basel II adoption as the instrument to assess the causal impact of bank regulation on SEO announcement effects. However, the stringency of regulation does not have a significant impact on the announcement effects of involuntary bank equity issuance.

Proyecto de mejoramiento para la estacion de servicio "La Americana S.A.S"

La estación de servicio “La Americana S.A.S” ha sido una de las primeras estaciones de servicio ubicada en Bucaramanga, dedicada a la comercialización y distribución tanto de gasolina como de los diferentes repuestos y accesorios para los vehículos, razón por la cual desde su fundación y hasta nuestros días, ha venido prestando un servicio destacado, efectivo y cumpliendo siempre con la demanda del mercado proporcionalmente a su consumo. Del mismo modo dicha experiencia dentro de este sector ha producido que con el transcurrir de los años, algunos entes privados y gubernamentales en su mayoría hayan querido hacer acuerdos y negociaciones organizacionales con dicha estación de servicio; claramente este tipo de alianzas estratégicas y negociaciones son de gran importancia ya que le dan el reconocimiento respectivo a La Americana y es así como esta organización recibe periódicamente ganancias y dineros fijos. Resultado de los acuerdos anteriormente mencionados, cabe resaltar que la mayoría de las ventas que realiza esta estación de servicio son producto de las compras hechas por los vehículos pertenecientes a las entidades gubernamentales y privadas en convenio; es importante mencionar que todas estas ventas se realizan vía crédito y por ende la cancelación del servicio correspondiente se hace uno o dos meses luego de prestado el servicio. Así mismo también se ha logrado evidenciar que el consumo por parte de los automóviles particulares con el transcurrir del tiempo se ha disminuido drásticamente debido a diversos factores (geográficos, competitivos y de procesos) tanto internos como externos y siendo una razón para que el total de las ventas y posteriores utilidades no sea el esperado. De continuar esto así en un futuro la empresa podría incurrir en serios problemas que afecten su participación dentro de este mercado. La alta dependencia de las ventas a crédito (entidades públicas y privadas) y la disminución continúa de las ventas de contado (particulares) está ocasionando que la Americana desde ya hace un tiempo tenga baja liquidez financiera y baja rotación de inventarios, así como la disminución considerada de sus utilidades, razón por la cual creemos que la implementación de un modelo de mercadeo así como la creación de un sistema para el conteo y supervisión de los inventarios ayudara a La Americana a poder superar esta pequeña crisis y poder ser una empresa perdurable durante los próximos años .

Rethinking Le Corbusier: Urban Design and History

It is generally assumed that Le Corbusier’s urban planning made a break with the past, and that the public spaces designed by him had nothing to do with anything that existed before – a conviction fostered by both the innovative character of his proposals and by the proliferation in his manifestos of watchwords that mask any evocation of the past – words like civilisation machiniste, l’esprit nouveau, l’architecture de demain. However, in his writings, Le Corbusier often mentioned the powerful analogy that exists between the architecture of other times and the logic of modern production. Vers une architecture, for example, contains a mixture of photographs showing silos, cars, aeroplanes, ships (i.e. the fruits of 19th and 20th century civil architecture and mechanical engineering) alongside photographs of Greek and Roman buildings. While Le Corbusier, at the end of the 1920s, claimed “I have only one teacher: the past; only one education: the study of the past”, a series of sketches in the first volume of the Œuvre complète, done during his youth at the archaeological sites visited during his Grand Tour, shows that his interest in the past went far beyond a simple reference.
