Single Pixel

Imaging with the use of a single pixel camera and based on compressed sensing (CS) is a new and promising technology. The use of CS allows reconstruction of images in various spectrum ranges depending on the spectrum sensibility of the used detector. During the study image reconstruction was performed in the LWIR range based on a thermogram from a simulated single pixel camera. For needs of reconstruction CS was used. A case analysis showed that the CS method may be used for construction of infrared-based observation single pixel cameras. This solution may also be applied in measuring cameras. Yet the execution of a measurement of radiation temperature requires calibration of results obtained by CS reconstruction. In the study a calibration method of the infrared observation camera was proposed and studies were carried out of the impact exerted by the number of measurements made on the quality of reconstruction. Reconstructed thermograms were compared with reference images of infrared radiation. It has been ascertained that the reduction of the reconstruction error is not directly in proportion to the number of collected samples being collected. Based on a review of individual cases it has been ascertained that apart from the number of collected samples, an important factor that affects the reconstruction fidelity is the structure of the image as such. It has been proven that estimation of the error for reconstructed thermograms may not be based solely on the quantity of executed measurements.

<p class="maintext">Reflected background infrared radiation is an important contributor to the aircraft total infrared radiation. A reverse Monte Carlo ray tracing method to compute the infrared radiation signature of aircraft was introduced. The impact of atmospheric and ground radiation on the long wave infrared radiation signature of aircraft at the altitude of 11 km is analysed. The flight speed is Mach 0.8. The horizontal detection directions, downward detection directions and upward detection directions are considered. The results show that in the horizontal plane, the ratio of reflected background infrared radiation to self infrared radiation is about 10 per cent in summer, and 7 per cent in winter; the ratio values distributed in the front and side of the aircraft are bigger than that in the rear; and the existence of atmospheric and ground infrared radiation makes the apparent radiance temperature of the lower part of the aircraft higher than that of the upper part of the aircraft.</p><p class="maintext"><strong>Defence Science Journal, Vol. 66, No. 1, January 2016, pp. 51-56, DOI: http://dx.doi.org/10.14429/dsj.66.8090</strong></p>

Abstract This study was aimed at determining the background of thought that underlies the education partnership in MAN Salatiga, the implementation of educational partnerships among the schools, parents, and social institutions in MAN Salatiga, and the impact of the partnerships among the schools, parents, and social institutions in the city Salatiga to improve the quality of schools, school culture, graduates, and parents. This type of research was a qualitative interpretive approach, which took place in MAN Salatiga, and community social institutions (Indonesian Red Cross, Indonesian National Sports Committee, Asmoro Budoyo Circle of Friends, Prana Shakti Jaka Tingkir Respiratory Self Defense College) in the city of Salatiga. Data were collected through interviews, observation, and document study. The data were then analyzed by following the stages developed by Yin and Stake, namely the stage of holistic analysis, embedded analysis, analysis of themes, within case analysis, and cross case analysis. The results of the study show that MAN Salatiga sees the need to utilize various resources in the community to overcome various limitations in the implementation of education in order to meet the demands of the community. The development of educational partnerships in MAN Salatiga is supported by social capital which is influenced by the type of school, initiative and interest, parental circumstances, school policy and political participation. Education partnerships in MAN Salatiga affect the quality of the schools, graduates, and parents. Keywords: Partnership, School, and Community Social Institutions   Abstrak Penelitian ini bertujuan untuk mengetahui latar belakang pemikiran yang mendasari kemitraan pendidikan di MAN Salatiga, pelaksanaan kemitraan pendidikan antara sekolah, orang tua, dan institusi sosial kemasyarakatan di MAN Salatiga, dan dampak kemitraan antara sekolah, orang tua, dan lembaga-lembaga sosial kemasyarakatan di kota Salatiga terhadap perbaikan kualitas sekolah, budaya sekolah, lulusannya, dan orang tua.

Purpose The purpose of this study was to identify levels of self-compassion in adults who do and do not stutter and to determine whether self-compassion predicts the impact of stuttering on quality of life in adults who stutter. Method Participants included 140 adults who do and do not stutter matched for age and gender. All participants completed the Self-Compassion Scale. Adults who stutter also completed the Overall Assessment of the Speaker's Experience of Stuttering. Data were analyzed for self-compassion differences between and within adults who do and do not stutter and to predict self-compassion on quality of life in adults who stutter. Results Adults who do and do not stutter exhibited no significant differences in total self-compassion, regardless of participant gender. A simple linear regression of the total self-compassion score and total Overall Assessment of the Speaker's Experience of Stuttering score showed a significant, negative linear relationship of self-compassion predicting the impact of stuttering on quality of life. Conclusions Data suggest that higher levels of self-kindness, mindfulness, and social connectedness (i.e., self-compassion) are related to reduced negative reactions to stuttering, an increased participation in daily communication situations, and an improved overall quality of life. Future research should replicate current findings and identify moderators of the self-compassion–quality of life relationship.

Swallow Function

Lung cancer is one of the most commonly diagnosed cancers across Northern America and Europe. Treatment options offered are dependent on the type of cancer, the location of the tumor, the staging, and the overall health of the person. When surgery for lung cancer is offered, difficulty swallowing is a potential complication that can have several influencing factors. Surgical interaction with the recurrent laryngeal nerve (RLN) can lead to unilateral vocal cord palsy, altering swallow function and safety. Understanding whether the RLN has been preserved, damaged, or sacrificed is integral to understanding the effect on the swallow and the subsequent treatment options available. There is also the risk of post-surgical reduction of physiological reserve, which can reduce the strength and function of the swallow in addition to any surgery specific complications. As lung cancer has a limited prognosis, the clinician must also factor in the palliative phase, as this can further increase the burden of an already compromised swallow. By understanding the surgery and the implications this may have for the swallow, there is the potential to reduce the impact of post-surgical complications and so improve quality of life (QOL) for people with lung cancer.
