ANN for Predicting Temperature and Humidity in the Surrounding Environment

Abstract: In this research, an Artificial Neural Network (ANN) model was developed and tested to predict temperature in the surrounding environment. A number of factors were identified that may affect temperature or humidity. Factors such as the nature of the surrounding place, proximity or distance from water surfaces, the influence of vegetation, and the level of rise or fall below sea level, among others, as input variables for the ANN model. A model based on multi-layer concept topology was developed and trained using data from several regions in the surrounding environment. The evaluation of testing the dataset shows that the ANN model is capable of correctly predicting the temperature with 100% accuracy

IDENTIFYNG VALUE –BASED ORGANIZATIONS

Owing to the day-by-day development of technology, global communication, and information networks, the dynamicity of investment and work forces has increased and the organizations such as join stock companies have no choice but to a new organizing era. Value-based organizations are one of the newest forms of today's organizations in which customers are as affecting the production and providing services, working and process strategies, and developing knowledge and competitive power, alongside with the members. "The organizations are always looking for the new methods and creating innovation, and they even name the value of the customer as their 'future source of competitive advantage'" (Kandampully & Khahn, 2004, p.398). Management based on value and value-based organizations are now affecting today's organizations, and values are regarded to be an undeniable source of competitive advantage. Hence, effectively managing the relationship with the customer, and creating and presenting values are the main mission of such organizations. This paper is attempting to provide a definition for the concept of value, and discuss the nature, their features and aspects, the importance, the advantages, key factors in their success, the phases of creating a value-based organization, expanding the values, the future of such organizations, their challenges, and also the role of the leaders in institutionalizing the valuesValue, Value-based Organizations, Value-based Management

Extraction of Monocyclic Aromatic Hydrocarbons From Petroleum Products Using Sulfolane as Industrial Solvent

Liquid liquid equilibria data were measured at 293.15 K for the pseudo ternary system (sulfolane + alkanol) + octane + toluene. It is observed that the selectivity of pure sulfolane increases with cosolvent methanol but decreases with increasing the chain length of hydrocarbon in 1-alkanol. The nonrandom two liquid (NRTL) model, UNIQUAC model and UNIFAC model were used to correlate the experimental data and to predict the phase composition of the systems studied. The calculation based on NRTL model gave a good representation of the experimental tie-line data for all systems studied. The agreement between the correlated and the experimental results was very good

El Conde de Galarza y el método crítico en la enseñanza de la filosofía

In 1908, public figures of the Egyptian civil society created the Egyptia University on the pattern of European universities. Foreign scholars belonged to its faculty including orientalists. The only Spaniard appointed as professor was Vicente Galarza y Pérez Castañeda, who taught philosophy in the years between 1915 and 1919. The article analyses the texts of his courses, taught in Arabic, and considers Galarza to be the first to apply the critical method in his university teaching

Optimization of hot press forging parameters in direct recycling of aluminium chip (AA 6061)

This study introduces a new approach of direct recycling using the hot press forging process that eliminates the two intermediate processes of cold-compact and pre-heating. This method leads to low energy consumption without intervening the metallurgical processes. In this study, the optimum of machined chips from high speed milling is recycled by hot press forging. The mechanical properties and surface integrity of the different chips were investigated. The performance of recycled aluminium AA 6061 chips in the mechanical and physical properties were compared with the original aluminium billet. Response surface methodology (RSM) was used to develop mathematical model of the effects on pre-compaction cycle, holding time and suitable pressure significant to the process. It is hoped that, utilization of primary metal could be fully utilized by direct recycling technique (hot press forging) introduced in this study and at the same time developing a sustainable manufacturing process technology for future needs

Interference coordination for LTE-advanced and FM broadcasting interoperability

The surest way to guarantee that multiple wireless systems can concurrently exist harmlessly, when operating in the same or adjacent channel, is by analyzing spectrum overlapping. This paper proposes a more accurate model to evaluate the interference power from co-channel and adjacent channel of orthogonal frequency division multiplexing-based long term evolution-advanced (LTE-Advanced) towards broadcasting frequency modulation systems at 800 MHz. Power spectral density overlapping factor is employed, and closed form of the interference power loss is derived. Numerical results demonstrate that the proposed method evaluates more exact interference power than the advanced minimum coupling loss (A-MCL) method, where the co-channel and adjacent channel interference powers are reduced by 1.3 and 3 dB, correspondingly, compared to that obtained using the AMCL method. This decreases the minimum separation distance between the two systems, which can eventually lead to efficient radio spectrum resources utilization

S}afwat Al-tafa

Salah satu sarjana muslim yang turut berpartisipasi dalam khazanah tafsir al-Qur'an masa kini adalah Muhammad ‘Ali alSabuni.Salah satu karya monumentalnya di bidang tafsir adalahS}afwat al-Tafa>si>r. Diakui oleh al-Sabuni sendiri, bahwa ia menulistafsir tersebut dalam rangka memberikan pemahaman kepada umatdi tengah-tengah kesibukan mereka yang kesulitan untukmembuka berjilid-jilid tafsir yang ditulis ulama sebelumnya. Di dalamnya, ia merangkum beberapa intisari kitab-kitab tafsir terdahulu dan memadatkannya dalam suatu kitab tafsir. Namun, dalam posisinya sebagai seorang tokoh yang pernah mengajar di Universitas Ummul Qura dan King Abdul Aziz Universtity, dalam aktivitas menafsirkan ayat, al-Sabuni juga menuai kontra dari para ulama di Saudi, terutama terkait tafsir ayat-ayat sifat. Tulisan ini akan membahas seputar al-Sabuni dan tafsirnya Safwat al-Tafasir serta penafsirannya terhadap ayat-ayat sifat yang menuai kontroversi
