On the spatial and temporal coherence of wireless vehicular short range channels
No full textWe consider spatial and temporal coherence of the vehicle–to–vehicle (V2V) wireless communication channel with focus on a suburban residential highway. The dominant reflectors in such an environment are vehicles passing in the adjacent lane and houses
along the road. Instead of treating the reflectors as point targets, the V2V short range propagation environment requires partitioning of the illuminated reflector side into
sufficiently small tiles. The channel transfer function is obtained as a superposition of specular reflections from the tiles, the line–of–sight (LOS) component, and the ground reflection. The tile size is selected to ensure that the ratio of the tile area to the tile–to–receiver distance satisfies the far field conditions. The reflected power is described by the tile radar cross section (RCS). The bistatic physical optics RCS model is adapted to account for the tile’s orientation with respect to the ray geometry. We apply the superposition model to the numerical analysis of two general scenarios
for a 22MHz channel in the 2.4GHz band. The first scenario considers a single vehicle reflector passing in the lane adjacent to the V2V communication pair. Both the vector network analyzer (VNA) experiments and the tiling model analysis illustrate that repositioning of the reflector, the transmitter, or the receiver by a few centimeters results in change of the signal power by several decibels. The second scenario analysis characterizes the channel coherence statistics for the
suburban residential highway. We consider the V2V single lane LOS and non–LOS geometries, where in the latter the receiver is shadowed by a large vehicle. The reflectors are both houses and vehicles passing in the opposite direction. The measure of channel coherence is the normalized spatial covariance calculated by correlating transfer functions corresponding to feasible receiver position pairs and performing spatial smoothing. The area of feasible receiver positions is divided into contiguous squares
whose size ensures wide sense quasi–stationarity within the square. Irrespective of direction the correlation remains high and a typical sedan roof usually does not provide sufficient spacing to obtain average inter–antenna correlation lower than 0.5. The upper bound on coherence time extends over the transmission time of multiple packets for systems in the considered band, and does not allow for usable time diversity.Ph.D.Includes bibliographical referencesIncludes vitaby Haris Krem
Studi komparasi konsep Zakiah Daradjat dan Dadang Hawari tentang gangguan mental dan penanggulangannya
No full textSkripsi ini disusun oleh Awaludin Haris (NIM 1101024) dengan pembimbing Drs. H. Machasin, MSi (bidang substansi materi) dan Syafruddin, M.Ag (bidang metodologi dan tatatulis). Skripsi ini berjudul "Studi Komparasi Konsep Zakiah Daradjat dan Dadang Hawari tentang Gangguan Mental dan Penanggulangannya". Kata Kunci: Gangguan Mental dan Penanggulangannya.
Metode penulisan ini menggunakan jenis penelitian kualitatif. Sumber primernya adalah karya Daradjat yang berjudul: Kesehaan Mental dan Hawari yang berjudul: Al-Qur'an, Ilmu Kedokteran Jiwa dan Kesehatan Jiwa. Sumber sekunder berupa karya Zakiah Daradjat dan karya Dadang Hawari yang lain. Adapun pengambilan data menggunakan penelitian kepustakaan (library research), sedangkan metode analisis yang digunakan adalah metode analisis komparatif.
Hasil temuan menunjukkan bahwa menurut Daradjat untuk menanggulangi gangguan mental adalah dengan mempertebal keimanan. Dalam buku tersebut diungkapkan tentang arti pentingnya keimanan atau ketauhidan dalam membentuk gangguan mental seseorang. Pokok-pokok keimanan yang diwajibkan bagi umat Islam, sangat penting artinya dalam menanggulangi gangguan mental, karena keimanan memupuk dan mengembangkan fungsi-fungsi jiwa dan memelihara keseimbangannya serta menjamin ketenteraman batin. Menurut Hawari, dari berbagai penelitian yang telah dilakukan oleh para pakar dapat disimpulkan bahwa untuk menanggulangi gangguan mental adalah melalui pelaksanaan rukun iman yang berjumlah enam dan melalui pengamalan lima rukun Islam.
Persamaan konsep Daradjat dan Hawari tentang gangguan mental dan penanggulangannya yaitu kedua tokoh itu mengakui bahwa tentang gangguan mental dan penanggulangannya adalah dengan agama, khususnya memperkuat keimanan. Adapun perbedaannya yaitu pertama, Daradjat telah dengan baik dapat menjelaskan secara rinci tentang bagaimana caranya beriman kepada Allah Swt itu supaya betul-betul menenteramkan batin. Sedangkan Dadang Hawari tidak menjelaskan bagaimana caranya agar orang bisa dengan mudah mengimani rukun iman yang keenam itu. Perbedaan lainnya yaitu pendekatan yang digunakan. Dilihat dari perspektif bimbingan konseling Islam, maka konsep iman/tauhid dalam menanggulangi gangguan mental menurut kedua tokoh tersebut sangat relevan dengan tujuan bimbingan konseling Islam yaitu membantu individu sebagai klien yang belum atau sudah terkena masalah menjadi manusia seutuhnya dan bertakwa kepada Tuhan Yang Maha Esa.
Rekomendasi: dengan memperhatikan konsep Zakiah Daradjat dan Dadang Hawari tentang gangguan mental dan penanggulangannya, maka komitmen agama, khususnya mengimplementasikan rukun iman yang berjumlah enam, maka dapat menanggulangi gangguan mental. Atas dasar itu, konsep kedua tokoh hendaknya dapat dijadikan pedoman dalam menanggulangi gangguan mental. Pedoman tersebut sangat berguna baik bagi konselor, masyarakat maupun kalangan akademisi
Hipertensi pada Sindrom Metabolik
No full textObesitas merupakan masalah yang banyak dijumpai baik di negara maju maupun di negara berkembang.
Seiring dengan meningkatnya kejadian obesitas, dikenal sindrom metabolik yang terdiri dari obesitas
sentral, resistensi insulin, hipertensi, dan dislipidemia berupa kadar trigliserida yang tinggi dan kolesterol
high density lipoprotein (HDL) yang rendah. Sindrom metabolik terutama disebabkan oleh obesitas dan
resistensi insulin. Selain sebagai tempat penyimpanan energi, jaringan lemak juga menghasilkan faktor yang
menyebabkan hipertensi. Jaringan lemak dapat menguraikan angiotensin dari sistem angiotensin-renin.
Pada obesitas, terjadi resistensi insulin dan gangguan fungsi endotel pembuluh darah yang menyebabkan
vasokonstriksi dan reabsorbsi natrium di ginjal dan menyebabkan hipertensi. Penurunan berat badan
merupakan faktor penting dalam tata laksana sindrom metabolik dengan hipertensi yang dicapai dengan
diet, latihan, medikamentosa atau gabungan hal-hal tersebut. Obat antihipertensi dapat dipertimbangkan
sebagai bagian pendekatan holistik dalam tata laksana.

Increasing the Performance of Passive Communication with Ambient Light
No full textMost wireless communication technologies have been using the Radio Frequency (RF) spectrum for decades. Due to the popularity of the Internet of Things (IoT), the RF spectrum has started to become densely populated. Researchers have begun to explore other bands of the electromagnetic spectrum that can be utilized as a communication media. One of the promising choices is the visible light spectrum.Visible Light Communication (VLC) refers to the wireless communication technology that utilizes the visible light spectrum. This spectrum is thousands of times wider than the Radio Frequency (RF) spectrum and is license-free. In VLC, data is transmitted by turning a light source on and off. However, not every light source can be controlled. Passive light sources such as the sun provide an immense amount of light that can be used for wireless communication if we can develop ways to modulate them. One of the researches that use ambient light to create a wireless link is LuxLink. LuxLink uses liquid crystal shutters to control passive light sources and provides low energy, reliable, and flicker-free (safe) communication. This thesis addresses several problems that the current LuxLink system has.We present LuxLink+, an extension of LuxLink that provides two main improvements. Firstly, the data rate of the system is relatively low (80~bps). To increase the data rate, we provide a thorough analysis of the system’s bandwidth. Afterward, we modify the modulation technique, which increases the data rate to 1000~bps at a range of 1.5~m.Secondly, the system has a static data rate, which means that the system cannot adapt its data rate to changes in the environment. We implement a rate adaptation algorithm that can change its data rate accordingly. LuxLink+ improves the average throughput of the system by up to 85 percent compared to LuxLink.Electrical Engineering | Embedded System
Performance investigation of an integrated wind energy system for co-generation of power and hydrogen
No full textIn this paper, a wind turbine energy system is integrated with a hydrogen fuel cell and proton exchange membrane electrolyzer to provide electricity and heat to a community of households. Different cases for varying wind speeds are taken into consideration. Wind turbines meet the electricity demand when there is sufficient wind speed available. During high wind speeds, the excess electricity generated is supplied to the electrolyzer to produce hydrogen which is stored in a storage tank. It is later utilized in the fuel cell to provide electricity during periods of low wind speeds to overcome the shortage of electricity supply. The fuel cell operates during high demand conditions and provides electricity and heat for the residential application. The overall efficiency of the system is calculated at different wind speeds. The overall energy and exergy efficiencies at a wind speed 5 m/s are then found to be 20.2% and 21.2% respectively

Leadership strategies for embedding sustainability and resilience in organizations with an emphasis on sustainable energy
No full textEfficient strategies to embedding sustainability in an organization are frequently linked to effective leadership. By design, changes in direction within an organization may lead to alterations in commitment or perceived significance of sustainability in organizations. While some organizational leaders are interested in embedding sustainability within a structure, other leaders believe in leaving the legacy behind and permanently influencing sustainability efforts. To confirm or dispel the underscored notion of the importance of leadership in embedding sustainability in organizations, a qualitative methodology approach to interviews, document analyses, and literature review is utilized. The research inquiry includes in-person interviews with top city staff and elected officials in a large Midwestern city and a review of the internal documents and reports. The end goal of the research is an examination of the role both elected and appointed officials have in embedding sustainability within cities, and whether a change in leadership may have an impact on continuity of sustainability implementation and
long-term viability of such policies. The paper focuses on the application of sustainable energy policies within a local government organizational structure as a mean of constructing a better understanding of leadership on sustainability implementation and embedment. While the further inquiry is needed, the research points out that an active partnership between city managers, administrators, and elected officials must be in place to support integrating sustainability from within and that sustainability thrives where exhaustive leadership support such
initiatives and efforts.Journal ArticleFinal article publishe
Measuring the Sustainability Impact in Local Governments Using the Quadruple Bottom Line
No full textSustainability is utilized by cities to enable a multifaceted, cross-sectoral approach for the betterment of communities and operational efficiency of organizations. Using a case study of the medium size local government in the Midwest and the city’s application of sustainability planning, this article focuses on a development of an expanded definition of the bottom line and a nascent approach to measuring and tracking sustainability-related efforts. The research provides an overview of measuring sustainability adopted by this particular city, using the target-specific,extended quadruple bottom line approach. The method attempts to address economic vitality, environmental quality, social equity, and governmental accountability through governance. The use of the quadruple bottom line to measure sustainability is linked to its annual budget planning and investments in transformation-related initiatives. While such an approach to measuring sustainability progress is unique in the United States, a number of cities in Australia have also adopted the quadruple bottom line approach to measure sustainability. Lessons in reporting sustainability efforts using the quadruple bottom line, in the context of an efficient and effective service delivery, can be applied to other local governments.Journal ArticleFinal article publishe
