Abstract:
Brain lower grade glioma (LGG) is a common type of glioma. The current treatment methods still have some limitations, and some LGG patients will inevitably continue to deteriorate after treatment. We found the value of lysosomal associated membrane proteins (LAMPs) in the diagnosis and prognosis of LGG, which helps to enhance the clinical understanding of LGG treatment and improved prognosis. We assess the role of LAMPs in LGG, via the publicly available TCGA database. We explored expression levels of LAMPs in LGG using GEPIA2, cBioPortal, and UALCAN databases. The correction of LAMPs expression levels with immune cell infiltration in LGG patient was assessed by TIMER database. The Lysosomal associated membrane protein 1 (LAMP1)/2/4 mRNA levels were significantly higher in LGG patients than in healthy controls. Morover, high mRNA expressions of LAMP1/2/Lysosomal associated membrane protein 3 were associated with poor overall survival. We found that the immune invasion of LGG was almost significantly correlated with the expression of LAMPs. The results suggested that mRNA expressions of LAMP1 and LAMP4 were significantly associated with histological subtypes in LGG patients. lysosomal associated membrane protein 2 and LAMP5 were significantly down-regulated expression in samples of TP53 mutant in LGG compared to TP53 wild type. In addition, Lysosomal associated membrane protein 3 and LAMP4 were significantly overexpressed in samples of TP53 mutant in LGG Enrichment analysis applied to each component indicated that biological function was primarily associated with series of pathways in synapse and immunity.

Abstract:
Lampu Gentur merupakan lampu asli kota Cianjur. Keberadaan lampu ini sudah ada sejak 1920. Seiring dengan berkembangnya jaman, bahan pembuatan lampu Gentur digantikan dengan bahan kuningan dan juga kaca yang berwarna-warni. Namun sayangnya hal tersebut tidak diiringi dengan perkembangan desainnya. Desain lampu Gentur dari dulu hingga sekarang hanya mencontoh dari lampu-lampu lain, khususnya bentuk klasik Kolonial Belanda dan Timur Tengah. Hal ini sangat disayangkan karena membuat Lampu Gentur tidak memiliki ciri khasnya tersendiri padahal para pengrajin sangat terampil membuat lampu yang berbahan baku kuningan dan kaca ini. Dilatarbelakangi kurangnya identitas desain lampu gentur, maka paper ini mencoba menghubungkan teori semiotic dalam perancangan ini menghubungkan simbol budaya Cianjur yaitu ayam pelung dan lampu gentur. Tujuan dari penulisan paper ini adalah pencarian identitas desain lampu gentur dengan pendekatan teori semiotic, diharapkan paper ini dapat memberikan model bagi desainer, bagaimana mendesain produk yang beridentitas budaya lokal. Metode yang digunakan adalah pendekatan teori semiotic pada proses desain. Hasil yang didapatkan adalah desain lampu gentur baru dengan mengambil ayam pelung sebagai inspirasi.Gentur lamps are one of Cianjur’s finest crafts. These lamps have been produced since 1920. At first, Gentur lamps were made based on the initiative of the Santri (Islamic priest) to make lighting by imitating Dutch people’s lamps that they used in their houses. Unfortunately, from the 1920s until now, Gentur Lamp designs haven’t developed much in terms of identity, always imitating what’s available in the market. On the other hand, Cianjur people are very skillfull in the craft skill of lamp making. From this lack of design identity background, this paper tries to elucidate the design identity of Gentur lamps by using semiotic theory, by connecting the cultural symbology of Cianjur, pelung chicken with gentur lamps. The purpose of this paper is to probe into design identity in Gentur lamp production by way of semiotics theoretical approach. In doing so, this paper postulates a cultural product design model that is meant to provide designers valuable reference material for designing successfully in a cross-cultural product modality. The final result being the new gentur lamp design with Pelung chicken as design inspiration.

ABSTRACT: It is necessary to periodically maintain lighting equipment in accordance with international standards. Contamination of lamps caused by long-term use of lighting equipment will result in loss of Luminous Flux and optical losses. The decrease in lighting performance poses a visual difficulty for drivers and causes accidents. In this study, the total Maintenance Factor is numerically examined by considering the losses of diffuser and lens for LED lamps used in tunnel lighting. The variation of luminaries performance with years considering Maintenance Factors as regards environmental conditions and features of the luminaries is evaluated to demonstrate the importance of tunnel lighting maintenance. Moreover, to show the importance of LED lamps Maintenance Factor, the variation of illumination levels of LED lamps is analysed under different Maintenance Factors. It is observed that enhancing Maintenance Factor would contribute to energy efficiency. ABSTRAK: Penjagaan peralatan cahaya secara berkala mengikut piawai kebangsaan adalah amat penting.

Abstract:
<p>Teknik penangkapan ikan dengan alat tangkap bagan di Indonesia khususnya di Kabupaten Barru umumnya masih menggunakan lampu merkuri yang mana membutuhkan energi listrik yang cukup besar. Salah satu alternatif untuk mengurangi penggunaan energi listrik yang besar ini dapat digunakan jenis lampu hemat energi seperti lampu Light Emitting Diode (LED). Tujuan dari penelitian ini adalah untuk mengetahui perbedaan jenis ikan yang dominan tertangkap, komposisi jenis, dan berat ikan tertangkap antara bagan yang menggunakan lampu merkuri dengan lampu LED. Penelitian dilakukan di perairan Kabupaten Barru-Selat Makassar, Sulawesi Selatan. Lokasi pengamatan terletak pada posisi 4°22’48,7"-4°33’47,8"LS sampai dengan 119°25’05,0"-119°33’42,7"BT. Pengamatan lapang/uji coba penangkapan dilakukan pada periode Oktober-Nopember 2012 dan April-Mei 2013 (sebanyak 50 Trip penangkapan). Hasil penelitian menunjukkan bahwa komposisi hasil tangkapan bagan yang menggunakan lampu merkuri dan lampu LED didominasi oleh ikan teri hitam, teri putih, kembung lelaki, tembang, cumi-cumi, dan peperek, masing-masing sebanyak 90% dan 83%. Dengan komposisi jenis hasil tangkapan yang demikian ini menunjukkan bahwa lampu LED dapat digunakan sebagai alat bantu penangkapan ikan karena mampu memikat jenis ikan target dan cenderung hasil tangkapannya sama dengan menggunakan lampu merkuri yang digunakan nelayan bagan. Terdapat perbedaan berat hasil tangkapan bagan yang menggunakan lampu merkuri dari pada yang menggunakan lampu LED, namun dari nilai hasil tangkapan tampak tidak berbeda. Berat jenis hasil tangkapan yang dominan tertangkap dengan lampu LED sebanyak17,49 kg/watt sedangkan lampu merkuri sebanyak 4,89 kg/watt. Hasil ini menunjukkan bahwa bagan dengan lampu LED mendapatkan tangkapan lebih banyak dibandingkan dengan bagan lampu merkuri.</p><p><br /><em>Fishing techniques with lift-net fishing gear in Indonesia especially in Barru Regency still usemercury lamp which require considerable electrical energy.

The composition of the catch between mercury lamps and LED lamps was dominated by black anchovy, white anchovy, indian mackerel, sardines, squid and golden ponyfish, respectively 90% and 83%. These results indicate that the LED lights can be used as fishing tools because it is able to attract the target fish species and tend to catch higher than mercury lamps that commonly used. The difference in weight of the catch by using a mercury lamp was statistically better than the LED lights, but the value of the catch of the two types of lamps are not statistically different. Catches based upon the weight per electrical power used to indicate that the LED lights (17.49 kg / watt) is better than themercury lamp (4.89 kg / watt).</em></p>

Abstract:
Although fluorescent lamp is a very efficient lighting device in daily life, still the high harmonic distortion and low power factor cause unnecessary energy consumption. In today’s environment demanding energy efficiency, it is important to reduce this energy loss by integrating an energy saving controller in the electromagnetic ballast of fluorescent lamps. The research presented in this thesis investigates the design and implementation of a new energy saving controller for electromagnetic fluorescent lamp network. The newly developed controller attempts to reduce power losses in both the electromagnetic ballasts and fluorescent lamps by regulating the incoming supply voltage to an optimum level. In addition, the new controller is able to adjust the illuminance level of working environment lightings under either dark or bright condition. Moreover, the function of the new controller is extended with time scheduling control capability, where the switching of lighting systems can be controlled at predetermined times based on occupancy schedule. Both simulation and practical results show that the implemented controller reduces energy consumption by at least 37.5%, by reducing the incoming supply voltage by 15%. In addition, it is desirable to have variable illuminance level control to decrease the energy losses. The experimental results show that the illuminance output level of electromagnetic ballast fluorescent lamps can be decreased by 50% using the new controller while maintaining unity power factor. Integration of the new energy saving controller into electromagnetic ballast fluorescent lamps impressively outperforms the existing electronic dimmable ballast. This new controller brings great ideas for energy saving in the use of fluorescent lamps.

Abstract:
Nowadays, lighting represents 20% of the global electricity consumption. Light can be produced using different technologies but more than 100 years after its invention, the incandescent bulb is still the most sold and one of the more used light sources. Of the total energy input in an incandescent bulb more than 90% is lost as heat while less than 10% is converted into visible light. However, there are alternative technologies which use up to 85% less energy for conventional lighting and there are even more efficient light sources for other purposes that if they replace completely all incandescent lamps over the world could reduce dramatically the global electricity consumption and greenhouse gases emissions. One may identify these alternative technologies mainly as LEDs and discharge lamps, but are they the unique alternatives? This thesis is focused on a new lighting technology whose name is LightLab and which is based on the field emission and cathodoluminescence concepts. This technology is under the research and development stage but prototypes have already achieved energy savings over 85% compared to incandescent lamps with a great color performance and with the advantage that it does not use mercury or other hazardous substances compared with discharge lamps. Thus, in the first part of the project all technologies and last improvements are studied while the second part analyses the market applications possibilities for the LightLab lamp considering the environmental perspective regulations and comparing the lamp with the other light sources. The result is that despite there are still some unknown parameters that need to be developed or improved, the lamp has a great potential for different applications fields.

Abstract

This thesis was conducted by Jenny Jansson and Maria Madsen, students at the Faculty of

Technology and Science and the Innovation and Design Engineer programme at Karlstad

University, during the spring 2008. The thesis covers 22,5hp for each student. Anna

Holmquist and Chandra Ahlsell at the company FOLKFORM were the ones who requested

the theis, their company are located at Stora Skuggan in Stockholm. Tutor for this thesis was

Lennar Wihk and the examiner was Monika Jakobsson of Karlstad University.

The given assignment came from FOLKFORM and the aim for the thesis was to create a

further development of two already existing lamps from an earlier collection at FOLKFORM,

“Jaipur” and “Modern Times”. The students used their creativity and ability to come up with

fresh ideas and new innovations with the lamps current design, but also considering

material, manufacturing methods and the environment.

Throughout the working process it was evident to create an exclusive concept yet a cheap

concept for each lamp, where the main criteria were to make the material enlighten the

feeling.

Apart from these concepts new ones for the packing was to be evolved, one concept for

each one of the lamps.

Through extensive research of materials, production methods and the market and consumer

needs, which generated in many ideas. The final stage was with the product of a concept

development. The chosen concept then generated in this thesis, with concept developing

and prototype developing, and four actual products, well conducted concepts of the lamps

Palmett and Rotation in the final stage.

The result of the thesis was, as mentioned above, four prototypes in 1:1 scale, an exhibition,

a PowerPoint presentation and a written thesis report.

Expectations are that FOLKFORM are willing to use the concept made by the two students in

their own making when it comes to the developing of earlier collections, were the lamps are

represented.

Abstract:
Today’s lighting technology is steadily becoming more energy efficient and less toxic to the environment since the passing of the Energy Independence and Security Act of 2007 (EISA) [1]. EISA has mandated a higher energy efficiency standard for lighting products and the phase out of the common incandescent lamp. This has led lighting manufacturers to pursue solid-state lighting (SSL) technologies for consumer lighting applications. However, two major roadblocks are hindering the transition process to SSL lamps: cost and quality. In order to cut cost, manufactures are moving towards cheaper packaging materials and a variety of package architecture construction techniques which may potentially erode the quality of the lamp and reduce its survivability in everyday applications. Typically, SSL lamps are given product lifetimes of over twenty years based off of the IES TM-21-11 lighting standard which does not include moisture effects or large operational temperatures [2]. A group of recently released off-the-shelf lamps have undergone a steady-state temperature humidity bias life test of 85°C/85%RH (85/85) to investigate the reliability in harsh environment applications. The lack of accelerated test methods for lamps to assess reliability prior to introduction into the marketplace does not exist in literature. There is a need for SSL physics based models for the assessment and prediction of a lamp’s lifetime which is being spearheaded by the DOE [3]. In order to be fully accepted in the marketplace, SSL lamps must be able to perform similarly to incandescent lamps in these environments, as well as live up to the lifetime claims of manufacturers. A lamp’s package architecture must be designed with performance factors in mind, as well as address some of the known and published package related failure mechanisms, such as carbonization of the encapsulant material, delamination, encapsulant yellowing, lens cracking, and phosphor thermal quenching [4]. Each failure mechanism produces the similar failure mode of lumen degradation predominately due to two contributing factors: high junction temperature and moisture ingress. The current state-of-the-art has focused on individual areas of the lamp, such as the LED chip, substrate material, electrical driver design and thermal management techniques. [5] – [16] Looking at the lamp as a whole is a novel approach and has not been seen before in literature. This work followed the JEDEC standard JESD22-A101C of 85/85 with a one hour interval of applied voltage followed by a one hour interval of no applied voltage [17]. This test was performed continuously for each SSL lamp until it became nonoperational, i.e. did not turn on. Periodically, photometric measurements were taken following the IES LM-79-08 standard at room temperature using an integrating sphere, a spectrometer, and lighting software. The overall health of the SSL lamps was assed using the relative luminous flux (RLF), correlated color temperature (CCT) and the color difference (Δu′v′) using the Euclidean distance of the CIE 1976 color space coordinates. Finally, a Weibull analysis was completed to compare the characteristic lifetime of the SSL lamp to the actual rated lifetime. An important result from this work shows that the rated lifetime does not come close to the actual lifetime when the SSL lamps are used in a harsh humid environment which is fairly common in outdoor applications across the U.S. Also, the photometric results are presented for the entire lifetime of each SSL lamp under test.

Abstract:
Thermal design is one of the most important issues in the development of compact self—ballasted fluorescent lamps as the demand for small yet powerful lamps is mounting. This paper proposes a simulation method that is based on a thermal network model for which a set of equations are developed. Some of the coefficients of the thermal network equations were determined experimentally using a simulated model lamp. The calculated temperatures are in good agreement with the measured temperatures. The work illustrates the usefulness of the proposed methodology in the design of compact self—ballasted fluorescent lamps.

Abstract:
Many illumination problems in microscopy can be solved easily and economically with fiber optics. Modes of illumination not provided by the designers of a microscope can be added. A modular illumination system involving a number of microscopes and sources can be assembled. Various types of illumination can be used simultaneously, e.g., bright field and dark field, transmitted and reflected. Realignment on changing lamps is simplified, since it is merely necessary to align the lamp relative to the fiber input end. Older microscopes with small lamps can be upgraded by using a fiber bundle terminated at the lamp filament location.

Abstract:
Pulsed infrared radiation generated by stimulated electronic Raman scattering (SERS) in a cesium vapor heat pipe is used to obtain diagnostic information on HBr in a tungsten halogen lamp. The output of a pulsed excimer-pumped dye laser is Raman shifted from the 470-474 nm region directly into the 3.8 m region. The IR beam is used in an absorption experiment to measure HBr, a key halogen carrying species in tungsten halogen (W-H) lamps, as a function of filament temperature in a W-H lamp. The beam traverses through the center of the coiled filament, and spectra are taken of the R- branch in the v=0 - v=l band for the lamp lit from 0-148 W, corresponding to filament temperatures of 296-2243 K. Molecular rotational temperatures and absolute HBr densities are then derived from the spectra.

Abstract:
In automotive lamps, an ideal paraboloid is the reflector shape of choice when lens optics is utilized. However, geometric distortions occur among manufactured automotive lamps. This paper discusses the effects of geometric distortions on spread, packing, and gradient of reflected light from automotive lamps. Relevant legal requirements set by Federal Motor Vehicle Safety Standard on the performance of automotive lamps are also discussed. A new parametric mathematical model is developed to represent the geometry of an ideal lamp reflector. A non-linear parametric estimation problem is formulated using the Box-Kanemasu modification of the Gauss method. An application of methodology is also presented in this paper. The results show significant distortions of paraboloidal reflector with respect to the ideal design-intent reflector geometry. The numerically calculated deviations of focal point, focal length and paraboloidal axis from the ideally designed reflector necessitate improvements in the tooling and the manufacturing process for better dimensional control.
