A new intelligent system design for cleaning the photovoltaic solar panel surface
Authors: MUTLUER Mümtaz , ERAT Abdurrahim
Published: March 2019

Nowadays electricity is generated by solar energy through photovoltaic solar cells and the system efficiency developed in this direction is being investigated. The efficiency of the photovoltaic panels used to transform solar energy into electricity is utmost importance. Dusting, equipment which are used for photovoltaic systems (DC conductors, inverter, panel interior design, etc.), shadowing, amount of radiation and many other factors affect to the efficiency of photovoltaic panels. Some of these are resolved in the installation of the system, while others are changed over time. For a good efficiency of the system during operation, at bottom, photovoltaic panel surface must be kept clean and so it can be absorb more effective solar radiation. The surface cleaning is empiric in many studies which manual or automatic; it can actually be by an intelligent system. In this study, an intelligent cleaning system based on fuzzy logic with arduino microcontroller was designed to automatically clean the photovoltaic panel surfaces. Thanks to the membership functions of the fuzzy logic as temperature, shadowing, dusting and output current of the panel, the designed system is enabled to operate efficiently. Two membership functions of each of these input functions have been determined. Detailed information about the membership functions of the inputs of the system is given in the system design section. These membership functions decide whether the system will be activated or not. The design purpose is to minimize the efficiency losses due to dusting and dirt on the panel surface and to allow for maximum electrical energy production. As a result, without waiting for the cleaning period, the loss of energy production is eliminated and the efficiency was increased by 15-20 percent.

Published: March 2019

In this study, the drag force of 1/33 scale bus model was improved by passive flow control method. The effect of passive air canal application to drag coefficient was experimentally and numerically investigated on a bus model. Experiments were carried out in the range of 3.8x105 - 7.9x105 Reynolds numbers. The similarity conditions were provided in experimental studies with the exception of the moving road. To provide the geometric similarity condition, the model bus was produced in 3D printer by scanning 3 dimensions. Reynolds number independence was used for dynamic similarity condition. The rate of blockage is 6.81% for kinematic similarity, which is lower than the rate of blockage accepted in the literature. Respectively 4.21%, 7.48% and 12.19% aerodynamic improvement achieved with 1, 3, and 5 passive air canals whose diameter 6 mm. Flow analysis was performed in Fluent® program of the model 3 bus to view the flow structure around the bus. The numerical results support to wind tunnel results. In this study the effect of obtained aerodynamic improvements by applied passive flow control method can decrease fuel consumption about 2-6% at high vehicle speeds.

Published: March 2019

The paper deals with the features of silos calculations as shells of rotation under asymmetric semi-uniform load. In accordance with the equation of equilibrium by using the momentless theory, the expressions for maximum value of linear longitudinal efforts in radial and meridional (longitudinal) direction and linear shearing force have been obtained. Analysis of design factor series of linear efforts and shearing force has been carried out in the paper. The opportunity of using the momentless theory to evaluate changes of linear efforts in radial direction and shearing forces has been presented. The quantitative assessment of a normal tension in laminas of silo body from the influence of maximum linear efforts and their connection with the tension from the pressure of the bulk material at the top of the capacity have been given. Full radial and contacting displacements of the capacity in the plane of cross section from the element of the wind load have been defined.

Authors: Podunavac Ivor , Crnjac Milić Dominika , Nenadić Krešimir
Published: March 2019

A proposal for developing a database model and a web portal for managing registration for student accommodation in a dormitory is given in this paper. The portal has two user profiles and corresponding functionalities; they are intended for users/students and administrators, respectively. In the process of application for student accommodation in a dormitory, every student has to provide data referring to GPA, i.e. academic achievement at school, level of education, university, parents’ status, household members, the number of siblings and their school age, and household monthly income. There are also extra conditions that could ensure direct allocation of accommodation at a dormitory. After the application process deadline has expired, the administrator can either accept or decline applications. At the end of the application process, the final ranking list can be published and made accessible. Advantages of using a web portal for the dormitory accommodation election and application process are e.g. better accessibility and the fact that students are exempt from delivering the necessary application documentation personally. In that way, costs are reduced, efficiency at work is increased and the possibility of making errors when entering and processing data is significantly lower.

Environment impact of a concentrated solar power plant
Authors: Bošnjaković Mladen , Tadijanović Vlado
Published: March 2019

More recently, there has been an increasing interest in the use of concentrated solar thermal energy for the production of electricity, but also for the use in cogeneration and trigeneration. In this sense, the increasing use of solar thermal energy in urban areas is expected, and its impact on the environment is inducing an increasing interest. The paper analyses the impact of concentrated solar power technology (linear Fresnel, parabolic trough, parabolic dish, and central tower) on the environment in terms of water consumption, land use, wasted heat, emissions of gases, emissions of pollutants that include the leakage of heat transfer fluid through pipelines and tanks, impact on flora and fauna, impact of noise and visual impact. The impact on the environment is different for different concentrated solar power technologies and depends on whether thermal energy storage is included in the plant. Water is mainly used for cooling the system, but also for cleaning the surface of the mirror. To reduce water consumption, other cooling technologies (e.g. air cooling) are being developed. The available data from the literature show large variances depending on the size of the plant, geographic location and applied technology.

Authors: Sembritzki Thorben , Thiele Lisa
Published: March 2019

Der Beitrag untersucht geschlechtsbezogene Unterschiede bei der Besetzung von Professuren an Fachhochschulen, etwa mit Blick auf die Zahlen von Frauen und Männern, die sich bewerben, ihre vorangegangenen Karrierewege und Bewerbungsmotive, den Ausstieg oder Ausschluss aus dem Verfahren, die mit der Annahme der Professur verbundene Veränderung der persönlichen finanziellen Situation und die erreichte Arbeitszufriedenheit. Der Untersuchung liegt ein exploratives Mixed-Methods-Design zugrunde, das qualitative ExpertInneninterviews mit quantitativen Analysen von Daten aus Berufungsakten und einer Online-Befragung von neu berufenen StelleninhaberInnen verbindet. Dabei zeigt sich, dass Frauen insgesamt kürzere Zeiten der beruflichen Praxis angeben als Männer, insbesondere in der Privatwirtschaft, und der Wechsel auf eine FH-Professur für sie eher mit dem Erreichen einer höheren Position und eines besseren Einkommens verbunden ist. Zum Schluss werden bestehende Forschungslücken identifiziert und mögliche Ansätze für weiterführende Forschung zum Karriereweg FH-Professur sowie zu Berufungsverfahren diskutiert.

Inwiefern können Universitätsromane Auskunft über die Verschränkung von Doing Science und Doing Gender im akademischen Alltag geben? Aufbauend auf Bourdieus Feldkonzept gehe ich dieser Frage anhand einer gendersensiblen praxeologischen Analyse von sechs zeitgenössischen deutschsprachigen Universitätsromanen nach. Zwei hervorgehobene Romanbeispiele zu den Praktikenkomplexen Gremienarbeit und informelle Zusammentreffen verweisen auf das Erkenntnispotenzial dieser Literatur für wissenschaftssoziologische Forschung. Doch müssen die Romane gleichzeitig selbst als distinktive kulturelle Praxis gelesen werden, durch die Wissenschaftlerinnen performativ fachliche Eignung abgesprochen wird.
Die Separierung der Geschlechter
Authors: Zwengel Almut
Published: March 2019

Interaktionen zwischen männlichen Geflüchteten und alteingesessenen Frauen werden seit den sexuellen Übergriffen in der Silvesternacht 2015 in Köln als problematisch gefasst. Hier wird ein Zugang zur geschlechterübergreifenden Interaktion gewählt, der von positiven Alltagskontakten ausgeht, nämlich der Interaktion zwischen Geflüchteten und ehrenamtlich für sie Engagierten. Leitfadengestützte Interviews mit 26 ehrenamtlich Engagierten werden in Anlehnung an die Grounded Theory analysiert. Die aus dieser Analyse heraus entwickelte Kernkategorie „Separierung der Geschlechter“ verweist vor allem auf herkunftskulturelle Zuschreibungen und/oder Sozialisation, aber auch auf weiblich dominierte Unterstützungsnetzwerke und auf geschlechtertrennende Angebote für Geflüchtete. Diese Separierung der Geschlechter führt zu Unsicherheiten bei geschlechterübergreifenden Interaktionen, insbesondere beim Umgang mit Nähe und Distanz. Das Ansetzen von kultureller Differenz wird in der Literatur skeptisch betrachtet. Kritisiert werden ein homogenisierender, statischer und deterministischer Kulturbegriff sowie die Reproduktion und Verstärkung von Vorurteilen und Stereotypen. Dennoch, in der Rekonstruktion von Interaktionen durch die befragten Engagierten spielt kulturelle Differenz eine entscheidende Rolle.

İnsanoğlunun, barınma ve
korunma ihtiyacından dolayı, yaşadığı yeri ve çevreyi düzenleme isteği mimarlık
eylemini başlatmış, yerleşik hayata geçmesiyle de ahşap, taş gibi malzemeleri
kullanarak mimari yapıların gelişim sürecini hızlandırmıştır. Mimari yapının en
temel biçimlendirme elemanı olan taş, aynı zamanda bir süsleme elemanı olarak
kullanılmış din, kültür ve estetik kaygılar ile birleşerek, duygu ve
düşünceleri anlatan bir araç olmuştur. Tarih öncesi çağlardan başlayarak
günümüze kadar gelişim süreci içine giren mimari yapılar, her türlü toplumsal
değişimden etkilenmiştir. Özellikle din ve sanat gibi kavramlar, mimari
yapıların değişip gelişmesinde önemli rol oynamıştır. Din
ve sanat; birbirine zıt iki kavram gibi gözükse de bu iki kavramın birbirleriyle
olan etkileşimini göz ardı etmek yanlış olur. Sanat; biçim ve içerik olarak
sosyo-kültürel düşünce yapısıyla gelişmiş, din yardımıyla da
somutlaştırılmıştır. Kapadokya
bölgesinde yer alan ve Aksaray’ın bir ilçesi olan Güzelyurt, kendine has tarihi
ve kültürel yapısının yanı sıra sivil ve dini mimari yapıları ile de ön plana
çıkmaktadır. 1924 yılına kadar Güzelyurt’ta yaşamış olan Rum halkından geriye
kalan, sivil ve dini mimari yapılarda görülen taş kabartmalar, din ve sanat
ilişkisinin somut bir örneğini ortaya koymaktadır. Bu çalışmada, Güzelyurt’ta
yerinde yapılan gözlem ve incelemeler sonucunda sivil ve dini mimari yapıların
dış cephelerinde görülen bitki, hayvan ve kadın figürlü taş kabartma
süslemelerin Hristiyanlık dini açısından taşıdığı önem ve dönemin sanat üslubu incelenmiştir. Ayrıca Güzelyurt’ta yaşamış ve
halen yaşamakta olan halk ile birebir görüşmeler (mülakat) yapılmış olup halkın
konu ile ilgili bilgi ve düşünceleri hakkında veriler toplanmıştır. Çalışmada;
din ve sanatın etkileşimi sonucu sivil ve dini mimari yapılarda görülen taş
kabartma süslemelerin yapım tekniği, şekli, kullanım amacı, anlamı, yeri ve
dönemi hakkında temel bilgilerin edinilmesi amaçlanmıştır. Araştırmalar
sonucunda dinin yaşama ait bir
gerçeklik olması, sanatında bu gerçekliği estetik bir güzellik katıp somutlaştırarak
yansıttığı görülmüştür. Ayrıca din ve sanat olgularının birbirinden büyük
ölçüde etkilendiği ve bu iki olgunun gelişip yayıldığı gözlemlenmiştir.

The Risk of Liquefaction Associated with Water Head Fluctuation in the Low-lying Area of Tokyo
Authors: Takeyama Tomohide , Honda Kazuya , Iizuka Atsushi
Published: March 2019

In the wide area of the eastern part of Tokyo, the ground level is less than mean sea level. This area is more vulnerable to disasters than other areas. If large flood damage such as storm surge should occur in this area, the disaster would be a long-term catastrophe. On the coast of Tokyo Bay, countermeasures have been taken by tide embankments and floodgates. However, considering the damage scale when it occurs, an analysis in this area is very important. In this area, ground settlement occurred and groundwater head dropped because groundwater excessively withdrew by the industrial purpose during the period of economic growth. Currently, the groundwater head recovers and the ground settlement has been subsided. However, due to the groundwater head fluctuation, pore water pressure distribution had been different from hydrostatic pressure distribution. Therefore, in the analysis in this area, it is necessary to consider past groundwater head fluctuation. In this research, the ground settlement and the distribution of pore water pressure are simulated from groundwater level fluctuation over the past 100 years. Then, we conducted the seismic analysis by input the distribution of effective stress calculating from the simulated ground water pressure. The sites analyzed in this research are Tokyo Sea Life Park at the mouth of Arakawa River.

Authors: Li Yanjun , Stankovic Radivoje , Ouyang Bing , Su Tsung-chow
Published: March 2019

Underwater inflatable structures (UISs) are distributed in an initial folded state for ease of transportation and deployment. They are able to morph into their intended geometry upon arrival at their destination. This morphing/inflation process can be driven by hydrogel beads, which swell when they contact water. In this research, we study the physical characteristics of tubular UISs with different configurations (length, slenderness, beads density). We fabricated sets of tubular UISs with nylon sleeves filled with different amounts of hydrogel beads and built a flexural test platform mounted on the test tank for the bending experiment. This work provides the experimental Young’s modulus of the tubular UISs under elastic and plastic deformations, and also discusses how the different configurations contribute to the tubular UIS’s stiffness.
Interaction Diagram of Rubberised Concrete Filled Square Hollow Sections
Authors: Elchalakani Mohamed , Dong Minhao , Karrech Ali
Published: March 2019

Rubberised concrete utilises waste material, prevents resource extraction and improves concrete ductility, however at the cost of reduced strength and stiffness. The performance of thirty rubberised concrete-filled single-skin steel tubes under combined loading conditions were systematically investigated and comparisons against six steel hollow tubular columns and beams were made. The experimental program consisted of three rubber replacement ratios, 0%, 15% and 30%, three load eccentricities and four tube sections with section slenderness (b/t, width/thickness) of 18 to 50. The results showed that the confined rubberised concrete and the restrained steel tube improved strength and ductility of the composite section. The rubberised concrete was more effective in delaying the premature buckling failure of the steel tube compared to the more brittle normal concrete. The rubberised concrete with 15% rubber replacement ratio showed a good balance of strength and ductility. The interaction diagrams obtained from the experiments and theoretical calculations were constructed and compared. The behaviours of the rubberised concrete filled steel tubes could be accurately predicted using existing design guidelines and safe designs can be produced. This study demonstrated the possibility of using rubberised concrete as a cost-effective solution to problems that require high moment and deformation capacity, such as the roadside barriers and columns in buildings located in seismic active zones.
Mechanical Behavior of Fiber-to-concrete Interface in Textile Reinforced Concrete: Theoretical Model
Authors: Cheng Shanshan
Published: March 2019

This paper presents a theoretical solution of a reinforcement-to-concrete interface model under pull-push loading. Expressions for the interfacial shear stress distribution and load-displacement history are derived for different loading stages. The full debonding propagation process is discussed in detail and the analytical solutions are verified by comparing with existing theoretical models. Results of the analytical solution are presented to illustrate how the bond length and local bond-slip law affect the interfacial bond behavior. While the case study in this paper is on textile reinforced concrete, the analytical solution is equally valid to similar mechanical cases such as rebar reinforced concretes.

Published: March 2019

Applications of hydraulic structures in low dams and diversion structures in countries like India, where sediment is a serious concern, demands a good expanse of research on the flow field and movement of sediment. The present study was focused on the non-uniformity in the velocity distribution along the flow direction and the movement of sediment over a ramp. The velocity distribution of the flow near and over the ramp was studied with the help of Acoustic Doppler Velocimeter. Experiments were conducted to study the mechanics and kinematics of movement of sediment particles. The movement of sediment particles over the smooth ramp was studied with the help of high-speed camera system. The particle velocity, acceleration, applied force and the angle of velocity vector were processed and analyzed from the captured images using digital image analysis techniques. The path of the movement of sediment particle was tracked. The vector results of the flow pattern indicated a very high amount of increase of the uplift velocity (y – component of the instantaneous flow velocity) component over a ramp. The sediment had very little movement for about 3.8 seconds at the beginning of the ramp and accelerated as it moved along the ramp in the downstream side. The path of the sediment movement over the ramp was found to be inclined by 25.6 to 35.7 degree to the horizontal axis which was almost parallel to the ramp (29.055 degree).

SISTEM PENENTUAN JARAK TERPENDEK BERDASARKAN DATA COORDINATE MENGGUNAKAN ALGORITMA DIJKSTRA DALAM KASUS PENGANTARAN BARANG SE-JABODETABEK
Authors: Agung Halim
Published: March 2019

Kasus diangkat berdasarkan rute-rute yang ditempuh para pengantar barang. Karena kondisi jalan yang macet dan memakan waktu lama, mereka seringkali kebingungan untuk menentukan rute terbaik. Berdasarkan variasi rute yang ditempuh dan jarak antara titik awal dan tujuan, kita dapat menghitung dan menentukan, jalur mana yang memiliki jarak terpendek dan terefektif.Dalam penelitian ini, algoritma Dijkstra diterapkan untuk menghitung jarak terpendek dari suatu titik ke titik lainnya dalam area Jabodetabek, berdasarkan banyaknya titik koordinat yang terdapat dalam database. Metode Iterative-Enhancement diterapkan dalam mengembangkan sistem ini. Pengumpulan data dilakukan melalui observasi pola rute yang sering dilalui dan studi literatur, disertai penelitian terdahulu tentang implementasi algoritma Dijktra. Sistem dirancang dalam beberapa tahapan, yaitu analisis kebutuhan sistem dan user, perancangan flowchart, perancangan DFD, perancangan database, hingga perancangan tampilan sistem.Hasil penelitian akan diwujudkan dalam bentuk sistem perangkat lunak berbasis web dan mencantumkan peta sederhana sebagai sarana untuk membantu para pengantar barang menentukan rute pengantaran yang lebih sesuai. Hasil penelitian diperoleh dari pengujian dengan dua kondisi (jumlah data) yang berbeda, yakni 2.056 dan 5.186 titik koordinat. Pengujian menunjukkan perbedaan jarak terpendek yang signifikan untuk masing-masing kondisi, di mana hasil perhitungan dengan kondisi jumlah data lebih sedikit tidak lebih efektif dibandingkan kondisi jumlah data lebih banyak.Dari pembahasan dan pengujian, disimpulkan bahwa algoritma Dijkstra sangat membanu dalam menentukan rute terpendek yang optimal. Didapati pula bahwa jumlah data sangat berpengaruh terhadap hasil perhitungan. Semakin banyak jumlah titik koordinat yang ada dalam database, semakin optimal hasil perhitungan yang akan diperoleh. Sistem juga menawarkan kemudahan bagi setiap pengguna melalui tampilan peta yang tertera sebagai visualisasi rute

We present a revised checklist of bat species occurring in the semi–urbanized region of the Central Valleys of Oaxaca, Mexico. The checklist is based on surveys using mist nets, recordings of echolocation calls, data from literature, and museum databases. Results show that the Central Valleys of Oaxaca have a species richness of 33 bat species belonging to 22 genera and five families. Species like the Mustached bat Pteronotus parnellii, the Western Red bat Lasiurus blossevillii and the Free–tailed bat Promops centralis were recorded after 32, 30 and 19 years respectively according to the records of the literature. We also recorded four species classified in some risk category according to either the Mexican government’s red list (NOM–059) or the IUCN red list. The recordings of the echolocation calls are the first from the region of Central Valleys of Oaxaca. Bat diversity in the Central Valleys of Oaxaca was underestimated and emphasizes the need for further research

Falling impact is one of the main mechanisms in the disintegration of packaging board in a drum pulper. In this study, the disintegration effect of falling impact was studied and evaluated with three different materials. Impact disintegration was isolated with a designed device that simulates falling in drum pulping. The falling heights studied were 2.75 m and 3.75 m. Repeated impacts from both of the studied distances were found to be similarly efficient at disintegrating a weaker material, such as testliner. This kind of behavior proposed that every material has an optimal falling height, from an energy consumption perspective. Another way to increase falling impact is to increase the mass of falling pulp. It was found that it is possible to increase the efficiency of the disintegration of stronger materials, such as kraftliner, with an increased falling mass. It was also noticed that motion after impact is important for disintegration as well. The number of impacts needed to disintegrate packaging board was found to be high. This raised the question of whether or not the falling of pulp is the only method for disintegrating packaging board. The results suggest that impacts by falling alone are not enough for the thorough disintegration of packaging board material; rather, other mechanisms are also involved.

A neutral deinking agent was applied for the deinking of laser printed papers under neutral or near neutral conditions of pH. The results showed that a deinking efficiency of 93% could be achieved with a laboratory made neutral deinking agent under optimum conditions. This neutral deinking agent, tagged as GWT, consists of anionic and nonionic surfactant, inorganic salt, etc. Optimum conditions were: GWT dosage of 2% (for dry recovered paper); pulping concentration of 10%~20%; pulping temperature of 60°C; pulping time of 25 min; conditioning time of 20 min; flotation concentration of 0.8%; and flotation time of 10 min. The neutral deinking technology is beneficial for the reuse of recovered paper due to its lower wastewater chemical oxygen demand (COD) and other chemical loads, thus resulting in lower treatment cost and environmental pollution compared with the regular alkali deinking process.
Effect of sheet temperature on web densification during calendering
Authors: Ghosh Ashok , Hart Peter
Published: March 2019

We used two different experimental methods to study the effects of sheet temperature at a given moisture content on web densification and sheet smoothness. Commercially prepared paperboard obtained from the WestRock Mahrt mill in Cottonton, AL, USA, was used in this study. Laboratory made handsheets prepared from Mahrt high yield kraft pine pulp were also used for portions of this work. Sheets were sealed in moisture-proof bags, heated to various temperatures, and calendered at multiple nip loads. The resulting changes in sheet density were determined. Additionally, a pilot-scale calender was modified to preheat the non-print side of the sheet before entering the nip. The modified sheet run allowed for an increase in the bulk temperature of the board with minimal changes in the moisture content of the print surface. Increasing the bulk temperature increased board density at a given print surface smoothness. We determined that increasing the board temperature by 14°C resulted in about a 1% increase in board density. The results of this study help explain the commercial results obtained with thermal gradient calendering.

Investigations were conducted to explore the use of anaerobic treatment options that may allow complete recovery of primary and waste activated sludge streams for incineration from a graphic paper mill with an integrated deinked pulp plant. The effective reduction of waste activated sludge quantity (55%–65%) was obtained by the anaerobic treatment of wastewater from the deinked pulp plant or by the anaerobic stabilization of the mill effluent from primary treatment, where chemical oxygen demand (COD) removal efficiency of 67.6% and 64.8%, and biogas potential of 440 and 496 m3/t CODremoved were achieved, respectively. The anaerobic treatment of wastewater and alkali hydrolysis of waste activated sludge decreased the dewatering properties of solids residue in treated effluent resulting in a negative impact on the sludge recovery energy balance. The addition of municipal wastewater to anaerobic treatment in the amount of 18 vol%, representing 10% of the total COD, increased the reduction of waste activated sludge to 78%, with a positive impact on the treatment costs and efficiency. Anaerobic treatment of the studied effluents may enable incineration of all mill sludge with a positive energy balance, a reduction of biological wastewater treatment operational cost by up to 83%, and mill conventional energy demands by up to 2.7%, resulting in total cost savings of up to EUR 5.2 (USD 5.60) per ton of paper.
Transmedia Historiography as Educational Practice: Narrativising Colombian Cultural Memory
Authors: Freeman Matthew
Published: March 2019

Both the biggest challenge and the biggest opportunity for understanding transmediality – itself the use of multiple media technologies to tell stories and communicate information – is the sheer breadth of its interpretation. Though primarily still seen as a commercial practice, this article explores the application of transmedia practices to the communication of history across multiple media platforms, questioning what this approach means to understandings of transmediality. More specifically, the article furthers discussions of the contribution that transmedia storytelling can make to educational practices, identifying new strategies for how transmedia storytelling is now being used to capture and narrativize historical memories, as media-based educational resources. To do so, the article focuses on the Colombian armed conflict and the Desarmados project, which I use to theorise how transmediality can work as historiography, allowing for not only a new way of experiencing and remembering history, but as that which can reshape history for the better, reconciling the past and the present.
Saturation Trails: The Acid Assay
Authors: Stephen Cornford
Published: March 2019

Saturation Trails is the collective title of a body of work conducted with the Archaeologies of Media and Technology research group at Winchester School of Art. The work investigates the materiality and operation of the digital image sensor, the ubiquitous photosensitive chip behind the lens of all phones, tablets, laptops, and cameras. To do this, I designed three experiments which would reveal the technics of the photosensitive semiconductor through which all our images are transduced. Image sensors were exposed using methodologies appropriated from the optoelectronics industry in which this component was developed, tested, and manufactured. The three techniques used were an infra-red laser, hydrofluoric acid and X-ray radiation.
