    399-403Association rule mining technique has been widely used in various applications. However, the abuse of this technique may lead to the discovery of sensitive information. Researchers in recent times have made effort for hiding sensitive association rules. But most of the techniques proposed are generally applied in binary dataset. It suffers from side effects of lost and ghost rule. Most business, medical and scientific domains has quantitative value for its attributes. Limited research is available for hiding sensitive information in quantitative data. The aim of privacy preserving quantitative association rule mining is to i. Prevent the discovery of sensitive information. ii. Not to compromise the access and the use of non sensitive data. iii. Be utilizable on large amounts of data iv. Not to have an exponential computational complexity. In this paper, a hybrid evolutionary algorithm is proposed for effectively hiding the sensitive quantitative association rules and for improving the utility of the database. The performance of the proposed system is compared with existing algorithm by measuring number of lost rules, number of ghost rules and number of modifications to the original data.</span

    New and effective aldimine types of corrosion inhibitors namely, N-methylidene octylamine (MOA), N-ethylidene octylamine (EOA) and N-propylidene octylamine (POA) have been synthesized. Their inhibition efficiency was investigated for the corrosion of mild steel in 1 M HCl solution by various corrosion monitoring techniques. A preliminary screening of the inhibition efficiency of the inhibitors was carried out by weight loss and gasometric studies. They were found to behave as good inhibitors in 1 M HCl solution. Potentiodynamic polarization measurements show that aldimines are mixed type inhibitors. The extent of the decrease in the hydrogen permeation current through the mild steel surface was studied by the hydrogen permeation technique and it was found that the decrease was in the order POA > EOA > MOA. Double layer capacitance and charge transfer resistance values were derived from Nyquist plots obtained from AC impedance studies. The adsorption of these compounds on mild steel from 1 M HCl solution obeys the Temkin adsorption isotherm

    Частотно-селективна поверхня (FSS) — це будь-яка тонка повторювана металева поверхня, призначена для відображення, пропускання або поглинання електромагнітного випромінювання відповідно до частоти хвилі. Вхідна плоска хвиля буде передана (смуга пропускання) або відбита назад (смуга зупинки) залежно від характеристик елементарної комірки. Це відбувається, коли частота електромагнітної (ЕМ) хвилі збігається з резонансною частотою компонентів FSS. Таким чином, FSS є просторовим фільтром, здатним пропускати або гальмувати електромагнітні хвилі певного діапазону частот у вільному просторі. Зараз FSS широко досліджені, і досягнуто значного прогресу в області їх проектування та реалізації для широкого спектру практичних застосувань, від мікрохвильових до оптичних частот. Представлена частотно-селективна поверхня, приєднана до нової круглої патч-антени з центральним живленням. Широка смуга від 5 ГГц до 6,2 ГГц досягається за допомогою монопольної діаграми спрямованості. Згідно з результатами моделювання запропонованої структури антени, її можна застосовувати в додатках діапазону ISM, бездротових аудіо- та відеосистемах та інших бездротових комунікаціях на частоті 5,8 ГГц. Він має симульоване максимальне підсилення 5,36 дБі та смугу пропускання 31,1%. У всьому робочому діапазоні всенаправлена діаграма спрямованості досить постійна. Загальні розміри антени становлять 27,34 x 27,34 мм2, включаючи структуру FSS, що робить компактну широкосмугову систему на 5,8 ГГц. Кругла патч-антена з ромбоподібним отвором у центрі ініціалізує перший резонанс на частоті 5,8 ГГц із розміром 20 x 20 мм2, а параметр продуктивності додатково покращується шляхом додавання структури FSS.A Frequency-Selective Surface (FSS) is any thin, repetitive metal surface designed to reflect, transmit, or absorb electromagnetic radiation according on the frequency of the wave. The entering plane wave will either be transmitted (passband) or reflected back (stopband) depending on the characteristics of the unit cell. This happens when the frequency of an electromagnetic (EM) wave coincides with the resonance frequency of the FSS components. As a result, an FSS is a spatial filter capable of allowing or inhibiting EM waves of a certain frequency range in free space. FSSs have now been widely investigated, and great progress is being made in the field of their design and implementation for a wide range of practical applications, from microwave to optical frequencies. The Frequency Selective Surface attached to the new center-fed circular patch antenna is presented. A wide band from 5 GHz to 6.2 GHz is achieved with a monopole-like radiation pattern. According to simulation results of the proposed antenna structure, it can be applied in ISM band applications, wireless audio and video systems and other wireless communications at 5.8 GHz. It has a simulated maximum gain of 5.36 dBi and a bandwidth of 31.1 %. Throughout the operational band, the omnidirectional radiation pattern is fairly constant. The overall dimensions of the antenna are 27.34 x 27.34 mm2 including FSS structure thus makes a compactable wideband system at 5.8 GHz. A circular patch antenna with diamond slot at center initialize first resonance at 5.8 GHz with a dimension of 20 x 20 mm2 and performance parameter is further improved by appending FSS Structure
