Tangenciális és radiális vízsugaras esztergálással megmunkált felületek érdessége alumínium ötvözeten
Authors: Kun-Bodnár Krisztina , Maros Zsolt
Published: November 2020

Az abrazív vízsugaras esztergálás egy új technológia a nehezen megmunkálható hengeres, vagy forgásszimmetrikus anyagok megmunkálására. Kétféle eljárás van elterjedőben: a tangenciális és a radiális módszer. A vízsugárral történő esztergálás egyik problémája, hogy a vágás valódi fogásmélysége nem egyezik meg a beállított értékkel. A radiális és tangenciális eljárás ugyanazon technológiai paraméterek beállítása esetén eltérő anyagleválasztást és felületminőséget eredményez. A cikkben egy alumínium ötvözet kétféle vízsugaras esztergálással megmunkált felületeinek érdességét hasonlítjuk össze annak érdekében, hogy megállapítsuk az egyes eljárások előnyeit, hátrányait és elsősorban egymáshoz való viszonyát.

Systematic Review of Computational Models for Human Brain Parcellation
Authors: Owate Patrick
Published: November 2020

Introduction: The human brain consists of four main lobar sections: Frontal lobe, Parietal lobe, Temporal lobe and Occipital lobe. Most of the existing models used for the parcellation of brain into these lobes have limited accuracy when applied to ageing brain. Aim: To systematically review the existing models of parcellating brain Magnetic Resonance Images, their strengths and weaknesses, and the possibility of using them for ageing brain. Materials and Methods: PubMed was searched combining search terms for Parcellation, Brain and Magnetic Resonance Imaging (MRI). Articles were considered if they met the following criteria: Parcellation method was indicated, imaging technique was MRI, high resolution anatomical T1-Weighted was used, lobar regions were parcellated, number of lobar regions was indicated. Results: The search resulted into 569 articles. 174 articles (7 from the list of references) were potentially relevant and their abstracts were read. Out of these, 108 were not relevant because they either focused on animal studies, sub-cortical segmentation or tissue segmentation. The full papers of the remaining 66 were reviewed. 39 articles met the inclusion criteria. Various parcellation models were reviewed and summarized into six groups: supervised learning, unsupervised learning, region growing, shape and appearance, energy-based and atlas-based models. Conclusion: All the existing models identified were developed for parcellation of young adult brains and none of them used age-related information. Atlas-based model was found to perform the best among all the models. Future work should consider extending atlas-based model by including ageing information which could make them perform well on ageing brain.
Investigation of Plasma Electrolytes Levels in selected Uterine Cancer Patients
Authors: Omoyajowo Koleayo
Published: November 2020

The balance of electrolytes in humans is not only considered pivotal for normal functioning of cells and organs but to recover from many metabolic disorders. Cancer patients are generally at risk for electrolyte imbalances from a myriad of causes. This study was undertaken to estimate electrolytes levels in uterine cancer patients and that of controls (healthy individuals). Clinical parameters were collected after obtaining informed consent from both patients and controls. Thus, venous fasting blood samples of freshly diagnosed uterine cancer patients and controls were collected to estimate electrolytes namely sodium (Na+), potassium (K+), chloride (Cl-), inorganic phosphate (PO43-) and bicarbonate (HCO3-). Na, K, Cl and PO43-were analysed spectrophotometrically (colorimetry) while HCO3- was biochemically analysed by titration. Results obtained in this study shows a significant increase (P<0.05) in the level of PO43- and Na+ in uterine cancer patients as compared with the control. However, a significant decrease was observed in the level of Cl- and HCO3- in uterine cancer patients when compared with controls. There was no significant difference in K+ level observed in both uterine cancer patients and controls. The evidence of associations between electrolyte imbalances and risk of developing uterine cancer as observed in this study are of particular importance in the prognosis, diagnosis and management of uterine cancer.

In our work, we present some fundamental aspects of the 5G business potential, where the key motives lay regarding the Industry 4.0 revolution and the innovation of 5G industrial architectures, including vendors, industrial players, and network operators.
Guerra e opinião pública nos Estados Unidos: o caso da Guerra do Iraque em 2003 / War and public opinion in the United States: the Iraq War in 2003
Authors: Damin Cláudio Júnior
Published: November 2020

O artigo aborda a relação existente entre guerra e opinião pública nos Estados Unidos. O artigo foca na análise do caso da Guerra do Iraque iniciada em março de 2003 durante os mandatos de George W. Bush. Esse conflito insere-se no contexto dos ataques terroristas de 11 de setembro de 2001, sendo parte constitutiva da chamada “guerra global contra o terrorismo”. A primeira hipótese de trabalho é a de que inicialmente e reproduzindo padrões históricos anteriores, a guerra foi amplamente aprovada pela população norte-americana, processo que se prolongou por alguns meses e influenciou decisivamente para a reeleição do presidente republicano em 2004. Como segunda hipótese assevera-se que, passado algum tempo, o humor da opinião pública sofreu uma inflexão, diminuindo a aprovação popular à guerra e tendo como importante desdobramento a derrota dos republicanos na eleição de 2008, com o conflito ainda em curso. Espera-se mostrar, portanto, como a Guerra do Iraque pode ser dividida em duas fases distintas, sendo a primeira de bônus para o governo de George W. Bush e seus correligionários republicanos e a outra de ônus a partir do crescimento do número de baixas militares norte-americanas e da crise de credibilidade do governo no que concerne às perspectivas de vitória definitiva no conflito.Abstract: The article discusses the relationship between war and public opinion in the United States. The article focuses on the analysis of the case of the Iraq War that began in March 2003 during the administration of George W. Bush. This conflict is within the context of the terrorist attacks of September 11, 2001, being a constituent part of the "Global War on Terrorism." The first hypothesis is that initially and reproducing previous historical standards, the war was widely approved by the American population, a process that was prolonged for a few months and influenced decisively to the re-election of Republican president in 2004. As a second hypothesis asserts that, after some time, the mood of public opinion has undergone a shift, reducing the public approval of the war and with the important effect the defeat of the Republicans in the 2008 election. It is expected, therefore, to show how the Iraq War can be divided into two distinct phases, with the first bonus for the George W. Bush and his fellow Republicans and other liens being from the growing number of U.S. military casualties and the crisis of credibility of the government with regard to the prospects of ultimate victory in the conflict.
Não abandone no escuro: a construção de confiança e os regimes de não-proliferação de armas de destruição em massa / Don’t leave in the darkness: the building of trust and wmd nonproliferation regimes
Authors: Santos Vieira de Jesus Diego
Published: November 2020

O objetivo deste artigo é investigar como os regimes de não-proliferação de armas de destruição em massa influenciam a construção de confiança entre grandes potências e Estados acusados de não seguirem ou violarem compromissos incorporados em tais regimes ou que os abandonam na contemporaneidade. O argumento central aponta que a confiança construída entre tais atores é menor quando 1) não se oferece a atores acusados de violar regras estabelecidas a habilidade de formular e implementar decisões sobre resultados antes controlados por outros, em especial relacionadas à preservação de direitos soberanos e inalienáveis dos Estados; 2) não se busca criar sistemas de supervisão depois da implementação das decisões e do conhecimento sobre suas consequências, os quais sejam menos custosos para que os Estados os implementem; 3) se definem modos de interação menos flexíveis que criem orientações excessivamente específicas sobre o comportamento a ser adotado. Abstract: The aim of this paper is to investigate how the regimes of non - proliferation of weapons of mass destruction influence the building of trust between major powers and states accused of not following or violating commitments incorporated in such regimes or abandoned them in the contemporary world. The central argument shows that the trust between these actors is lower when 1 ) regimes fail to offer actors accused of violating established rules the ability to formulate and implement decisions on results previously controlled by others, in particular related to the preservation of sovereign and inalienable rights of states; 2) regimes do not create systems of supervision after the implementation of decisions and the knowledge of its consequences, which are less costly for states to implement them, 3) less flexible modes of interaction are created and very specific guidelines for the behavior are adopted.
A decade of compulsory silence: Censorship of Edvard Kocbek’s literature after his forced retirement
Authors: Gabrič Aleš
Published: November 2020

Edvard Kocbek was a renowned Slovenian writer who started writing already in his youth. In 1941, he became a member of the Liberation Front and the struggle against the occupiers. At the end of the war and shortly after it, he held important and esteemed positions in the power structure, but he lacked any real clout. After the political action taken against him in 1952, he was prevented from publishing his works for nearly a decade. Although Yugoslavia did not employ censorship in the form of formal bans at the time, the authorities would prohibit the publication of his poems, articles, or books behind the scenes. Through the archival documents of the most prominent political bodies in Slovenia, the present contribution outlines the manners in which this behind-the-scenes censorship was employed: at closed meetings, the authorities would decide what could not be printed, and the publishers and editorships had to comply with these decisions. These bans were not caused merely by the contents of Kocbek’s works, based on the Christian and existential persuasion, but rather by the fear that because of his reputation, Kocbek could become the focus for the association of cultural workers of different persuasions and the formation of a group that could eventually become a significant political factor.

„Produkt niedostępny w ilościach sprzed wojny, ale za to tej samej jakości”. Uwagi o reklamach jako źródłach historycznych
Authors: Saryusz-Wolska Magdalena
Published: November 2020

Artykuł omawia cechy reklamy jako źródła historycznego w oparciu o przykłady z prasy niemieckiej, ukazującej się bezpośrednio po drugiej wojnie światowej. Był to okres skrajnych wręcz niedoborów i niedostępności większości produktów codziennego użytku. Na tym tle rzucają się w oczy kolorowe reklamy nierzadko luksusowych marek. Co mówią nam te obrazy o wczesnym powojniu w Niemczech? Artykuł kładzie nacisk na rozumienie reklamy jako medium formującego normy społeczne, które nie tyle odzwierciedla minioną rzeczywistość historyczną, ile ją projektuje. Reklama okazuje się zarazem narzędziem wytwarzania ciągłości między epokami, nie tylko pod względem gospodarczym, ale też estetycznym i kulturowym. Autorka formułuje zatem sugestię, by ekonomiczną funkcję reklamy przesunąć w badaniach historycznych na dalszy plan i wykorzystać ją raczej w badaniach historii rozwoju kapitału społecznego.
Inne obrazy przeszłości. Uwagi o destabilizacji dyskursu polskiej historii sztuki w najnowszych wystawach muzealnych
Authors: Słodkowski Piotr
Published: November 2020

Autor stawia pytanie o to, jak wystawy muzealne mogą pracować na rzecz przepisania wybranych palących problemów polskiej historii sztuki. Wybiera trzy projekty wystawiennicze (2019–2020), by rozwinąć możliwe odpowiedzi. Argumentuje, że Ekspresje wolności wspierają myślenie o „potencjalnej historii (sztuki)” (Ariella Azoulay): alternatywnych geografiach, powiązaniach i cyrkulacjach ludzi i idei. Streng/Włodarski unaocznia z kolei materialność artefaktu artystycznego jako źródła historycznego, tym samym czyniąc z historii sztuki kluczowy fragment badań nad Zagładą. Zwraca wreszcie uwagę, jak wystawa Nigdy więcej robi użytek z historycznej sztuki antyfaszystowskiej i w tym „retro-aktywnym” geście (Rem Koolhaas) podejmuje problem współczesnej sprawczości społecznego zaangażowania artystycznego.

Teoria quasi-obiektu
Authors: Serres Michel
Published: November 2020

Tekst jest fragmentem książki Michela Serresa La parasite [Pasożyt] wydanej w 1980 roku. Kluczowe pytanie, jakie stawia autor tekstu, dotyczy zbiorowości, której funkcjonowanie zasadza się na pasożytowaniu, życiu kosztem innych organizmów, zarówno ludzkich, jak i nieludzkich. Wspólnota tworzy się w ruchu podmiany (wikariancji), odstępowania siebie na rzecz innych, w łańcuchu przekazywania „ja”. Podobnie rozumiana jest przez autora podmiotowość – jako nigdy niezakończony proces wyzbywania się siebie, wymagający porzucenia koncepcji bytu na rzecz relacji.
Odzyskać Einfühlung. Poszukiwania formuły radykalnej empatii we wczesnej twórczości Haruna Farockiego
Authors: Piasecki Michał
Published: November 2020

Wychodząc od bliskiej lektury tekstu Einfühlung Haruna Farockiego, autor analizuej kształtowanie się tej tradycji empatii i postawy polemicznej wobec niej, ze szczególnym uwzględnieniem poczucia porażki i retrospektywności postulatu odzyskania Einfühlung przez tradycję krytyczną. Autor przygląda się roli fotografii cierpiących ciał w procesie kształtowania się niemieckiej sfery publicznej w czasie wojny w Wietnamie. Stara się pokazać złożoność strategii krytycznych wobec przekazu masowych mediów poprzez rekonstrukcje polemiki Farockiego z ruchami terrorystycznymi. Analizuje parodystyczne wykorzystanie estetyki telewizyjnej w filmie Ogień nie do ugaszenia i wpisuje je w tradycje walki z tabloidowymi mediami. Interesuje go przewartościowanie relacji ciała i obrazu, które może pozwolić na przekroczenie wzorca empatii poprzez identyfikacje i pomyślenie „Einfühlung, która wywoływała efekt obcości”.
Empathy: Primal Scenes
Authors: Mościcki Paweł
Published: November 2020

The article is a constellation of readings and references, which are meant to bring closer not so much the definition of empathy in the context of images as to reconstruct its conditions of possibility; to trace the dynamics of its generation in and through visual works. The hypothesis around which this essay unfolds is the conviction that in every contact with an image, the key role is played by something imageless, which refers primarily to the other senses, but also structurally relates to an experience in which the ethical and aesthetic component are inseparable from each other. By analyzing specific texts that refer to this structural dimension of the empathic experience, the author concludes his argument with an analysis of selected visual works that shed additional light on his deliberations.

Homeostaza ośrodkowego układu nerwowego a sen: rola układu cholinergicznego, glutaminianergicznego i GABA-ergicznego oraz ich interakcje w przełączaniu pomiędzy stanami behawioralnymi i fazami snu.
Authors: Cieślik Paulina , Wierońska Joanna M
Published: November 2020

Sen jest złożonym procesem, który jest ściśle regulowany przez wiele neuroprzekaźników. Aktywacja lub hamowanie obszarów zaangażowanych w przełączanie pomiędzy stanem czuwania a snem jest uzależnione od homeostazy pomiędzy uwalnianym glutaminianem a GABA. Znaczącą rolę w tych procesach spełnia również acetylocholina, która odpowiada za utrzymanie stanu czuwania, a także moduluje przejście w fazę REM.

Zapewnienie odpowiedniego przełączania pomiędzy stanem czuwania a snem, a także pomiędzy snem NREM a REM jest kluczowe dla prawidłowego funkcjonowania organizmu. Procesy te zachodzą na zasadzie negatywnych interakcji pomiędzy kilkoma ośrodkami w mózgu. Regulacja przełączania pomiędzy stanami i fazami snu została przyrównana do działania przełącznika bistabilnego (flip-flop switch). Taki mechanizm działania zapewnia szybkie i definitywne zachodzenie opisywanych procesów bez występowania stanów pośrednich. Zaburzenie procesu przełączania może prowadzić do fragmentacji snu lub wystąpienia narkolepsji.

Role of Nutraceuticals in Health Promotion and Disease Prevention: A Review in the Indian Context
Authors: Chhabra Sheena , Bakshi Apurva , Kaur Ravineet
Published: November 2020

Nutraceuticals have been around for quite some time. As the nomenclature suggests, they are placed somewhere between food (nutra-) and medicine (-ceuticals) in terms of their impact on human health. Researches have focused on the impact of various types of nutraceuticals on health, their efficacy in health promotion and disease prevention, and often on suitable uses of certain categories of nutraceuticals for specific health issues. However, we are still far from utilizing the immense potential of nutraceuticals for benefiting human health in a substantial manner. We review the available scholarly literature regarding the role of nutraceuticals in health promotion, their efficacy in disease prevention and the perception of nutraceuticals' health benefits by consumers. Thereafter we analyze the need for regulation of nutraceuticals and various provisions regarding the same.

Public policies directed to territorial management governance strategies could have a significant influence on activities, like tourism. In fact, such policies could profoundly shape the regions. Besides, in territories with a socio-economic basis depending on tourism, such policies could present even more meaningful consequences in the region. Thus, throughout the evaluation of the public perceptions (surveys), the present research intends to produce further insights into how those regional policies could affect tourism activities in the Azores Islands.The study shows that more than 90% of the participants believe that Spatial Planning and Planning strategies directly impact tourism in the Azores Archipelago. Also, the research shows that the growth and development of Azores are sustainable and focusing on foreign high market segments. However, Azores do not have adequate territorial planning strategies and projects to increase residents’ quality of life.
An Adaptive Technique for Estimating Traffic Intensities for a Network in Random Markovian Routing
Authors: Bhattacharjee Debanjan , Zhuang Yan
Published: November 2020

We propose an efficient method for estimating a vector of parameters that characterize the node-tonode traffic intensities in a network. The estimation procedure is free from any initial estimate which is often difficult to choose for iterative procedures that occur in maximum likelihood estimation or method of moments. The procedure discussed here updates the information from a continuous chain of data until a stopping variable decides the final sample size and the estimate. More importantly, it considers the cost of logistics in sampling. We discuss important desirable properties of the estimation-procedure under the assumption of Poisson distribution. Data analyses reveal a highly accurate estimation and demonstrate a fast convergence

Authors: Paul Amal , Chacko Shone , Mukundan Arya
Published: November 2020

Coronavirus disease (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has attained the distinction of a global pandemic, aff ecting more than 185 countries. The impact of COVID-19 in the practice of cardiology extends beyond the clinical Cardiovascular (CV) manifestations of the disease. Many treatment modalities used in the treatment of COVID-19 have direct or indirect eff ects on the CV system. Management of CV disease in patients with proven or suspected COVID-19 infection warrants modifi cation of existing practices and guidelines so as to suit the changed health care environment. The safety of health care personnel becomes an important consideration in the setting of this highly contagious pandemic. Furthermore, long-term cardiovascular consequences of COVID-19 need to be determined for appropriate follow-up of patients recovering from the infection. We review the data available till date on the various aspects of the impact of COVID-19 on the heart and the practice of cardiology.
A focused ethnography of how endoscopy practitioners utilize capnography in sedated patients
Authors: Aldossary Deemah Nassir , Milton Sherran
Published: November 2020

The literature shows that respiratory complications are common with sedation. Given the inherent risk, capnography monitoring is recommended whenever sedation is administered. We aimed to explore sedation practitioners’ behavior patterns and perceptions regarding capnography monitoring during endoscopy sedation and examine how capnography influenced clinical decision making when assessing respiration. We conducted a focused ethnography with triangulated observations and semi-structured interviews, and we purposively sampled and recruited five sedation practitioners as participants at a hospital in Saudi Arabia. Through data analysis, we identified representative themes and found cultural differences between anesthesia practitioners and nurses when using capnography during sedation. Anesthesia practitioners linked safety and the use of capnography to maintain adequate respiration, while nurses believed capnography was a secondary supportive monitor to patient observation and assessment. Findings also captured the unique cultures and values of each professional group to be associated with the varying perceptions. We also identified several factors facilitating and barring adequate utilization of capnography. In conclusion, professional culture, hospital policy, knowledge and previous experience with capnography guided the monitoring practice of endoscopy practitioners when assessing respiration during sedation.
Assessment of quality and suitability of groundwater resources for industrial and irrigation purposes, Dire Dawa, Ethiopia
Authors: Gebremikael Girmaye Haile , Dawod Aman Hussien
Published: November 2020

The groundwater demand of Dire Dawa has increased recently due to the expansion of irrigation and the industrial sector in the city. Groundwater used for irrigation and industry was studied. Eighty-two samples were used to analyze physicochemical using different indices like Langelier index (LSI), Ryznar index (RSI), Aggressive index (AI) and Larson-Skold index (LRI). Parameters of Sodium Absorption Ratio (SAR), Residual Sodium Carbonate (RSC), Dissolved Sodium (%Na), Magnesium hazard (%Mg) statistical and spatial distributions were analyzed and programmed with Excel, Arc GIS, and Diagrams software. Results showed that pH, Mg2+, Cl- were found to be within the limit for industrial use. The groundwater corrosion indices mean values of LSI, RSI, AI, and LRI obtained were 0.29 ± 0.28, 6.4 ± 0.5, 12.20 ± 0.24 and 1.4±1.57, respectively. LSI, RSI results indicated a moderate scale-forming tendency of the groundwater. AI values were within low to no corrosion rates in all zones. Because of Cl- and SO42-, LSI showed some localized corrosion properties at kebele 01 and 09. Parameters like pH, Conductivity, Na+, HCO3- and Cl- ion were within permissible limits for irrigation. The irrigation indices (meq/l); SAR, RCS, Na% and Mg Hazard were calculated to be 1.33, -2.17, 21.5%, 45%, respectively. The EC was within the permissible limit but was significant. The low values of SAR, RCS, Na% indicated that the groundwater can cause lower alkalization (Sodium hazard) effect. In conclusion, all the parameters of the groundwater sources were categorized as good for irrigation. However, corrosion indices elaborated the groundwater scaling problems and may also be aggravated with temperature and heat-related industrial equipment.

When Research Interviews are More Therapeutic Than Therapy Interviews
Authors: Gale Jerry
Published: November 2020

This brief report presents some preliminary results of part of a study currently being conducted (Gale, 1992, May). The study is a qualitative analysis of a couple's and therapist's perspective of meaningful moments in therapy using Interpersonal Process Recall (IPR) (Elliott, 1986). The methodology of this study involved the collaborators (aka: subjects) in a manner that was self-reflexive and recursive (see Steier, in press). The impact of the study was such that the research interviews themselves were reported to have greater therapeutic impact than the therapy. Following eight sessions of marital therapy, the couple reported that therapy was not helpful, and they were together only because of the children. Following the second IPR interview, which was post-therapy, the couple reported that the interview was very useful and therapeutic. This seemed to occur, in part, from three different factors. These factors include: the relationship of the couple to the researcher; the contextualization of the research talk; and clarifying procedures used by the interviewer.
COMPARATIVE DISCOURSE ANALYSIS ON MEDIA RELATED TWEETS OF PRESIDENT DONALD TRUMP AND SENATOR BERNIE SANDERS
Authors: Şakiroğlu Hülya Ünsal
Published: November 2020

This study aims to investigate the language and the attitude of two well-known U.S. politicians, U.S. President Donald Trump and Bernie Sanders, towards media in their social media messages on Twitter microblogging site. The comparison and analyses are performed using Fairclough’s analytical framework of the socio-cultural approach of Critical Discourse Analysis (CDA): text, discourse practice, and sociocultural practice. The data consists of 50 non repetitive recent media related tweets collected from personal accounts of Trump and Sanders. The findings indicate that Trump uses an informal, direct, and provoking communication style to construct and reinforce the concept of a homogeneous people and a homeland threatened by the dangerous and biased other (media) while Sanders having more democratic, liberal language, and focuses on more tangible, important social issues such as environment, education, and health problems as he himself prominences often. Moreover, Trump employs positive self-presentation and negative other presentation to further promote his agenda via social media. Bernie Sanders on the other hand criticize media for a set of different reasons. Although they both criticize the media extensively in their usage of Twitter, discourse analyses indicate that the underlying political motivations are fundamentally different.

Design of Reconfigurable Patch Antenna in Frequency, Pattern, and Switchable Polarization
Authors: Zhang Yan , Sun Da , Dong Tao , Yin Jie
Published: November 2020

In this paper, a circularly polarized frequency, pattern, and polarization switching antenna is proposed. The antenna consists of an octagonal patch, a narrow octagonal ring and four diamond-shaped parasitic patches on the top layer. Two feed points of the radiating patch are connected to a Wilkinson power divider loaded with the phase reconfigurable transmission lines on the bottom layer. Reconfiguration of the polarization and pattern is realized by using PIN diodes as switching components. By controlling the bias voltage across the varactors, various narrow frequency bands can be achieved. The proposed antenna operates at a frequency tuning range from 1.96 to 2.03 GHz. The radiation pattern can be switched among five cases in yoz-plane and xoz-plane, with the switchable polarization between left- and right-hand circular polarization. In addition, these three types of reconfiguration can be controlled independently.

Authors: Khan Shahid , Ali Hazrat , Shah Syed , Ali Haider , Tanougast Camel
Published: November 2020

In this work a novel miniaturized frequency reconfigurable Dielectric Resonator antenna using Artificial Magnetic Conductor (AMC) surface is proposed. The prototype is set to work for 5G mid-band frequencies and Wireless Body Area Network (WBAN) applications. The work consists of two parts: firstly, the miniaturization of the prototype using AMC surface and secondly using the same AMC surface to reconfigure the frequency to another wireless application. Using AMC surface, the DR volume is reduced by 85% percent. Connecting the AMC unit cells through ideal switches (micro-trip slabs) re-configures the DR for different frequency. The overall performance observed before switching as well as after switching in both the cases is promising. The design is fabricated for performance analysis. A close agreement is reported between simulated and measured values of the reflection coefficients, radiation pattern, gain and efficiencies. The prototype has stable radiation pattern for both the operating frequencies. The impedance bandwidth values for both the resonance frequencies are 14.2% and 16% respectively. The prototype has a maximum gain of 6.8dBi and a maximum efficiency of 88%.
