Students’ expectations from graduate studies in heritage (tourism) management

This article provides certain key aspects that might help to further develop academic heritage education. These have been discussed within brainstorming and round-table sessions carried out by World Heritage students at BTU Cottbus-Senftenberg. Important aspects regarding expectations, current issues and prospective career opportunities were selected after these sessions. With the idea of our International Master Programme in mind, the results of this work have been summarized to identify what makes a good focus to Heritage Studies and further strategies to improve this discipline. It was concluded that international and interdisciplinary approaches should serve as the basis to facilitate personal research interests, critical thinking, a sense of student community and how all these can be applied to a future professional career. External students, faculty members and heritage professionals are invited to join this debate

Green coffee beans feature extractor using image processing

This study offers a novel solution to deal with the low signal-to-noise ratio and slow execution rate of the first derivative edge detection algorithms namely, Roberts, Prewitt and Sobel algorithms. Since the two problems are brought about by the complex mathematical operations being used by the algorithms, these were replaced by a discriminant. The developed discriminant, equivalent to the product of total difference and intensity divided by the normalization values, is based on the “pixel pair formation” that produces optimal peak signal to noise ratio. Results of the study applying the discriminant for the edge detection of green coffee beans shows improvement in terms of peak signal to noise ratio (PSNR), mean square error (MSE), and execution time. It was determined that accuracy level varied according to the total difference of pixel values, intensity, and normalization values. Using the developed edge detection technique led to improvements in the PSNR of 2.091%, 1.16 %, and 2.47% over Sobel, Prewitt, and Roberts respectively. Meanwhile, improvement in the MSE was measured to be 13.06%, 7.48 %, and 15.31% over the three algorithms. Likewise, improvement in execution time was also achieved at values of 69.02%, 67.40 %, and 65.46% over Sobel, Prewitt, and Roberts respectively

Smart Wheelchair with Dual Control using Touchpad and Android Mobile Device

The general objective of the design was to develop a touchpad controlled Android-based electronic wheelchair. It aimed to construct the Android-based circuitry and program for the path finding mechanism of the drive system and interface the Arduino-based circuit to the electronic wheelchair setup. It was designed to evaluate the system in terms of the speed of the electronic wheelchair, reliability of the sensors to avoid obstacle, and ease of use of the wheelchair. C Programming Language was used by the system to control and manipulate the microcontroller, Gizduino AtMega644. The Android application was programmed using the Java Language and Eclipse as the IDE. Its ports were used to interface input and output devices such as the ultrasonic sensors, infrared proximity sensor, touchpad, Bluetooth module, motor and motor driver. There was a satisfactory rating for the evaluation of the system while the Android software was rated excellent as a navigational controller

Informe de la experiencia profesional dirigida a jóvenes vinculados al programa bandera joven perteneciente a la parroquia sagrada familia del barrio Bello Horizonte municipio de Popayán.

Tablas, graficas, encuestas.El proyecto consistió, en realizar un trabajo de cartografía social que permitió identificar el tipo de conflictos que se presentaban en la comuna, su grado de intensidad y ubicación espacial. Atendiendo a ello se realizaron reuniones con los ediles y la comunidad para efectuar un reconocimiento de las problemáticas sociales presentadas; también se realizaron algunas entrevistas y se aplicó una metodología participativa que permitió a la gente elaborar sus propios mapas cartográficos. La ubicación de estos conflictos en un mapa, hizo visibles los focos de violencia y los lugares que requerían ser atendidos por la Casa de Justicia con una estrategia coordinada y mayor claridad. De esta manera y partiendo de la información arrojada en esta primera etapa, lograron determinar el carácter de los conflictos más comunes que rondaban entre la violencia intrafamiliar, conflictos penales, entre vecinos, pandillas y droga; y las áreas de mayor vulnerabilidad. Es así como entre los resultados logrados hasta el momento por este proyecto, se tienen el haber hecho un reconocimiento de esta parte de la ciudad separada por las dinámicas de violencia que allí tienen lugar, y en ese recorrido, se valoraron las potencialidades de la gente. Así mismo también han logrado conocer algunos de los orígenes de la violencia urbana que alimenta la violencia política y que tienen relación con la situación económica de las familias, la falta de oportunidades educativas y culturales, y la inestabilidad laboral. De igual manera se inició un proceso de concienciación entre los habitantes de la Comuna y la “Casa Móvil” de Casa de Justicia, que consiste en trasladar la institución a los barrios para acompañar los procesos de solución pacífica.No Abstrac
