Published: January 2022

Aliances between organizations have become an increasingly popular method of development. Dynamic markets, coupled with the increasing costs of doing business, have resulted in a significant increase in the use of strategic alliances. Firms in many industries must develop new capabilities in many areas, ranging from tecnologically development to manufacturing process, from plant economies to marketing and distributin, and they must do so quickly. Developing such competitive capabilities with limited resources is the core of strategic alliances, which allow firms to recast their competitive strategies in response to głobalization.
Mapping COVID-19 in a Region Using IP Geolocation and Fuzzy Inference System
Authors: Aris Widodo Anang , Muslim Alamsyah
Published: January 2022

The spread of COVID-19, which is getting faster every day, has made people wary. If residents suffer from the symptoms and risks of COVID-19, they are afraid and ashamed because they feel ostracized by their neighbors, relatives, and families. It is a shame and fear of reporting that causes the transmission of COVID-19 to accelerate. Therefore, it is necessary to create a system that can answer the problem, namely a system that can detect first aid symptoms and risks of COVID-19 suffered by residents, so that residents know their health status without checking the health of the COVID-19 task force in each area. The system is made by reading the location of residents who report their health to know where they are and their health status. A method for reading the location of system users based on IP addresses is called IP Geolocation, which stands for Internet Protocol Geolocation. The determination of the health status of residents is in the category of Negative COVID-19, ODR, ODP, PDP, or Positive COVID-19 using the Fuzzy Inference System (FIS) method. The IP Geolocation and FIS results will be displayed on a map (google maps). Implementing this system will make it easier for the Government to monitor the spread of COVID-19 based on public reports and information. By testing using the black box method based on partition equivalence with seven facilities in the system, one mistake makes the facility a weakness of IP Geolocation.

Pandemic, Participatory Culture and Reinvention of Everyday Life
Authors: Saba Ayon Hadi
Published: January 2022

How do we define participation during a pandemic? Are we in an era that requires reinventing our physical space and our modes of participation to build a new society? The novel coronavirus has deconstructed social space as we know it, and significantly disrupted our participation in its spheres. Today we are witnessing new forms of space, in the light of the ongoing pandemic and its impact on our participation, physical space and digital culture. This article demonstrates changes that occur in the physical and connected spaces that form our “new virtual urbanism” (Doueihi, 2011). It describes participation practices in natural parks in a Geneva-Switzerland and the Pays de Gex-France, distinguishing three types of spaces: the pre-pandemic space, the confinement space and the deconfinement space. It shows how socio-cultural practices changed in relation to the configuration of the space and the use of digital technology. Will we need to reinvent our space to encourage participation? The answer lies perhaps in considering the development of our digital traces and harvesting them in organized projects with rules, purpose, administration, management and governance. In this sense, digital participation becomes full and efficient when it relies on the process of building a memory and includes those who find themselves excluded from this new world.

Multimodal User Interface, Enabling of Assistive Robots
Authors: Mortazavi Batool , AliShirvani Nasrin
Published: January 2022

Multimodal user interface is a kind of user interface which is able to receive various high data and produce various types of output in reaction to it. Though human – robot interaction is based on human and computer interaction, it is more complex than human – computer interaction due to considerable increase in the number of inputs and outputs. Increase in parameters results from mobility of robot and human, interaction of robot and objects and necessity for three-dimensional understanding of the environment. Security is one of the main concerns in human – robot interaction. One of the novel applications of robots is caring for people with physical disability and aged people. Due to some limitations of these patients, simplicity of communication and no need for learning by the clients, in one hand, and presence of various inputs, versatility and automatic adaptation of robot performance and ability to respond to incomplete input, on the other hand, is palpable.

Published: January 2022

Given the uncertainties associated with orexin A and obesity, the present study was conducted to identify the effect of endurance training and HIIT on orexin A and lipid Profile in obese adolescent boys. For this purpose, 35 healthy, inactive and obese boys (aged mean 15.5±0.69 years, BMI percentile equal to or higher than 95% and BMI 28.72±2.20 kg/m2) were divided into three equal groups, control, HIIT and endurance training groups in a semi-experimental, randomized and double-blind design. HIIT and endurance training groups participated high intensity interval and endurance running in eight weeks, three days per week. Orexin A, LDL, HDL, TG, TC Plasma levels and WHR, BF%, BMI and VO2max were measured before and 48 hours after the last session of training. Data as mean ± SD using repeated measure ANOVA was analyzed at α ≤ 0.05. Training was caused significant lower of triglycerides and anthropometric parameters such as body fat percentage, body mass index and waist to hip ratio (P < 0.05). But, significant differences were not observed in orexin A, total cholesterol, LDL and HDL plasma levels, in control and experimental groups (P > 0.05). Therefore, endurance training is more effective than HIIT in improvement of obese adolescent boy’s body composition and HIIT is more effective than endurance training to reduce triglycerides. However, changes that may not be in line with changes occurring in orexin A. Thus, it is recommended to repeat like this study in multitimes training with control of sleep, nutrition, puberty changes.

Authors: Jahanbakhsh Heydar , Siahkalroudi Morteza Lotfipour
Published: January 2022

In the past three decades, the contemporary Urbanism theories and models have paid attention to energy management issues according to their approach on the construction and development of cities. Therefore, recognizing their different dimensions of energy management, approaches and policies, and also a comparison among the theories themselves can help to obtain a more comprehensive understanding of energy use. This comparative study aimed at identifying approaches, policies and procedures of urbanism in the field of energy management. It applied a descriptive-analytical approach to investigate seven important contemporary theories from the perspective of energy management. This research represented that energy management in modern theories of urban development do not merely means reducing energy consumption but it focuses on controlling and preventing energy loss, energy efficiency, use of natural renewable and sustainable energy and energy recovery. Meanwhile, there is a meaningful relationship between the theoretical approaches of urbanism’s theories and energy management. The theories focused on planning and based on land use and transportation have paid attention to reduce consumption, and theories focused on urban design have paid attention to renewable energy, prevention of  energy loss, and recycling of it. Despite the differences in approach, policies and procedures regarding energy management, all theories under studies consider the issue of energy management seriously. Their differences caused by differences in their theoretical approaches to urbanism (planning and design); however, all of them emphasis on reducing energy use.

Authors: Somarin Abbas Mirzaei , Shirin Mohammad Reza Deldadeh
Published: January 2022

One of the most important reasons of the existence of different types of files with media (audio or video) content, is achieving compression and less size, while preserving quality. In terms of fast transportation of files between equipment and networks and decrease of the required storage space, compression have always been under attention and action. Considering what was mentioned, in general, the concept of compression can be divided into two classes of lossy and lossless. In the lossy method, a part of data is omitted, but in the lossless methods, no data is omitted for compression. At the end of this article, a lossless compression method is presented using Imperialist competitive algorithm for compression. The proposed algorithm tries to achieve a more optimized color for the image color-map, so that it increases the compression rate. The simulation results indicate that the proposed algorithm can perform the compression by 43 percent and show its superiority compared to other similar methods.

Authors: Jafari Hadi , Jalali Peyman , Varahram Sina , Hassanejad Reza , Ettefagh Mir Mohammad
Published: January 2022

A voice is a sound which is created by vibration of the vocal cords, which means that, the vocal cords approach to each other by passing the air through the larynx and followed by different sounds. This vibration is under the influence of the statuses of tongue, teeth and lips, as well as the other effective factors. This vibrating air causes some minor changes around the individual speaker, which is called the voice. Some of the most important procedures in the voice signal analyzing is the signal processing methods in frequency and time-frequency domains; the most conventional approach in frequency domain is the Fast Fourier Transform (FFT) method, on the other hand the time-frequency signal processing methods can identify the frequency components of the signal and extract its time-varying characteristics; moreover they are effective tools for extracting the information of non-stationary signals. Time-frequency analysis methods can be classified into linear and nonlinear categories. The Short-Time Fourier Transform and the Wavelet Transform are the most conventional linear methods. This paper investigates the differences in the energy levels of explosive consonants in voiced mode and unvoiced mode using the most conventional frequency analysis and linear time-frequency analysis methods; these approaches are very effective and profitable in phonetic science and biomedical engineering science in order to diagnosing and determining the severity of laryngeal diseases and brain injuries. Results of this study indicate that the energy level of explosive consonants in voiced mode is more than unvoiced mode; also using Fast Fourier and Wavelet Transforms presents the results in better resolution and better image quality than the short-time Fourier Transform.

The castles are some of these monuments so that it has been tried in this essay to define the position of their architectural structure with study on the castle during historic and Islamic periods. According to objectives in this investigation, initially some issues have been examined and studied including geographic and historic position, typology, and their architectural importance and features and the buildings in terms of architectural structure and porcelains and materials and eventually it has been concluded that there are 9 castles in Andimeshk geographic zone. Construction of Lour, Gasem, Chalat, and Mongareh castles belongs to Sassanid (historic) period. Two Chalat and Mongareh castles have been employed as two very important security citadels in Islamic periods during Seljuk Dynasty and repeatedly during Ilkhanate Era. But two zones of Lour and Gasem castles have been inhabited again during Ilkhanate Dynasty while Sarqala or Amir Seif castle, which its building was formed primarily during Ilkhanate period, would be probably concurrent with aforesaid castles. Early formation of Hosseini, Chehar Borji (four towers), Bardel, and Couran (Kooru) castles belongs to Safavid period, which has been built by Luristan rulers and repaired during Qajar Dynasty.

Simultaneous Electricity Price and Demand Forecasting in Smart Grids
Authors: Asgari Vahid , Larmai Ali Rahmani
Published: January 2022

Today's competitive world and economy is heavily dependent on electrical energy. Since electricity cannot be stored and producing more or less than the required needs may lead to some losses. The electric charge forecasting and pricing are considered as the main factors in planning and decision-making for future development plans and operation of power systems. In the future smart grids, electricity consumers will be able to react to changes in electricity prices. The total response of consumers to price could potentially shift the demand curve in the market. As a result, prices may vary from original projections. In this paper, a forecasting framework is proposed that offers such dynamics in predicting the electricity price demand. In this framework, a mechanism based on principles of data mining data mining to determine the patterns in response to changes in consumer demand and prices are used. In this model, the weather conditions (temperature and humidity), the days and special holidays are considered. And the results are expected to be done hourly, daily. Simulation results of the proposed method for forecasting demand and prices, which were obtained using the Australian electricity market, indicates that error is less compared to the previous methods.

A review of accounting basis adjustments
Authors: Karbasian Mojtaba
Published: January 2022

Governmental accounting and national accounts are two types of reporting system as interrelated with different purposes. The financial data of public institutes are provided in public accounts by the governmental accounting system. The public accounts are the initial data of national accounts. This issue is of great importance in European Union as these reported values are considered as the main measure of monitoring the monetary policies of Euro. As the national accounts reporting is based on accrual system in accordance to European system of national and regional accounts, the governmental accounting system of different countries has its own special reporting system and the cash basis in the budget reporting is combined with the accrual basis in financial reporting. Thus, in case of converting the data from the governmental accounting to national accounting, we need some adjustments in audit basis. This study explains and compares the governmental accounting with national accounts and different analyses in their accounting basis to perform adjustments on the estimations of governmental accounting data to compute the macroeconomic ratios including budget deficit and it is effective on reliability and comparability of data. Also, similar researches are applied in different countries.

According to representation theory, hope of future good news stimulates the managers to postepone bad economic news in order to gain extra return. But in fact conservatism in accounting, as an influential control mechanism in identifying the good versus bad economic news, prevent the managers from over-optimism and provides a framework for identifying economic affairs. Therefore, it is the intention of this research to study the aforementioned challenge through analyzing the relation between conservatism, accrual persistence asymmetry and stock return. Conservatism is considered as independent variable of the research and accrual persistence asymmetry and stock return as dependent variables. Moreover, Basu’s model its used for measuring conservatism and to control risk, stock return is moderated in extent. Admitted firms in Tehran’s Bond Exchange from 2009 to 2015 constitude the date of the present research from which a sum of 66 firms (462 year-firm) are placed within the sample data of this research. The assumption of the research are tested via analyzing coefficient variables?regression modeling findings of the research suggest that there exists no meaningful relation between resistance of accrual items and stock return and another analysis rejected the existence of such relation has been rejected which suggested that law makings and standards are weak in a way that provide the ground for manipulating the real activities altimately leading to increased operational risks.

Published: January 2022

Doubtless, architecture is one of the invaluable and profitable resources of countries holding the necessary infrastructure of the industry or seeking to build them. Tourism is a complex of phenomena and relations coming from interactions among tourists, capitals, hosting governments and communities, scientific institutions, transformation firms, and hosting and control of the tourists. One of the lucrative tourist sources is artistic and architectural phenomena which stand for the civilization of each country as civilization is a combination of symbols and historical and cultural revelations that are evidences for fort and identity of a nation and their persistence among other nations and civilizations. One of these revelations and symbols is historical houses and textures that have mostly been museums or places of interest that are restored today. In these buildings, Iranian art and architecture reveals itself from the past and demonstrates its mutual effect. Taking care of cultural identity in building, least use of natural resources and life qualities, this architecture meets a lot of principles which are financially efficient. The aim of this paper is to introduce the patterns of sustainable architecture in old Iranian architecture; it also examines old houses particularly Jalil Arazi house in Ghazvin which is a bright example of sustainable architecture. Climate, ecology, atmosphere, building’s body, appropriate form and beautiful design are some of the main factors in sustainable architecture. That’s why Iranian architects have been welcome to anything looking good to the eye and have revealed it in traditional architecture; some of these visual scenes include patterns of decorative designs, stucco, glass works, sash windows, brickworks, etc. This paper has implemented on biblical and archival method by survey and is provided the results as a paper.

Introduction of Expectation Tourism
Authors: Masoumi Masoud
Published: January 2022

Tourism is divided into different kinds and branches. Dividing tourism into different types can be done through better recognizing, planning and managing the tourism in different local, urban, and regional levels. Political borders, geography-economic characteristics, and tourists' motivation for tourism are considered as the basic indicators of dividing tourism into different types. Meanwhile, tourists' motivation for dealing with tourism activities is very important. Doing tourism activities by tourists is linked to special motivations. Study of different nations' history reveals that the men is always desiring and expecting Utopia and imagine an ideal society and future. A short look at some samples in the world shows that these imagines stem from something more than religion beliefs. From the past centuries, Believers of Utopia expect a person called "Savior" who guides communities to Utopia, hold special ceremonies, and do something. For example, millions people, from all over the world, annually visit attractions, connected to these motivation in some way. Expecting the Savior reappearance and visiting tourism attractions is the main issue of this article. In this article, the author has separated visiting the attraction places of different regions with expectation motivation from other kinds of tourism and called them "Expectation Tourism".

Authors: Ghahremani Davod , Mobasherpour Iman , Mirhosseini Seyed Abolkhasem
Published: January 2022

Nano tricalcium phosphate particles were prepared by a wet method from aqueous solutions and characterized using TEM, XRD, and BET-N2 adsorption measurements. The potential of the synthesized nano tricalcium phosphate particles to remove Pb2+ cations from aqueous solutions was investigated in batch reactor under different experimental condition. The effects of initial concentration, adsorbent dosage, contact time and temperature were studied in batch experiments. The sorption of Pb2+ by nano-TCP increased as the initial concentration of lead ion increased in the medium. Various thermodynamic parameters, such as G°, H° and S° were calculated. Thermodynamics of Pb2+ cation sorption onto nano-TCP system pointed at spontaneous and endothermic nature of the process. The pseudo-first order, pseudo-second order and intraparticle diffusion kinetic models were applied to study the kinetics of the sorption processes. The pseudo-second order kinetic model provided the best correlation (R2 > 0.999) of the used experimental data compared to the pseudo-first order and intraparticle diffusion kinetic models.  The maximum Pb2+ adsorbed was found to be 4761.90 mg/g. It was found that the sorption of Pb2+ on nano-TCP was correlated well (R2 = 0.982) with the Langmuir equation as compared to Freundlich and Dubinin–Kaganer–Radushkevich (D-K-R) isotherm equation under the concentration range studied. This study indicated that nano-TCP could be used as an efficient adsorbent for removal of Pb2+ from aqueous solution.
Étude minéralogique de l’or et de ses minéraux accompagnateurs sur le pourtour du massif cambro-ordovicien de Serpont, Belgique
Authors: Bruni Yannick , Hatert Frédéric
Published: January 2022

Le massif de Serpont est un petit massif cambro-ordovicien localisé au centre de la province du Luxembourg, entre les villes de Libramont-Chevigny, Bras et Libin, au Sud-Est de la Belgique. Celui-ci est bordé de plusieurs ruisseaux traversant principalement le conglomérat Lochkovien de la Formation de Fépin. L’or alluvionnaire se retrouve sous la forme de paillettes et de grains, le plus souvent « modifiés », et contenant parfois des inclusions de quartz. Les analyses chimiques ont décelé des teneurs inférieures à 7 % en poids d’argent, excepté pour un grain correspondant à de l’électrum, ainsi que des traces de cuivre et de fer. Tous ces éléments sont répartis de manière homogène dans chaque grain. L’origine de l’or est probablement à la fois filonienne, mis en place lors de la formation de fluides métamorphiques tardi-varisques (500 °C et 300-400 MPa) dans un contexte de « shear zone », et détritique, c’est-à-dire contenu au sein des conglomérats et arkoses éodévoniens de la Formation de Fépin.

The upcoming 4-m International Liquid Mirror Telescope (ILMT) facility will perform deep imaging (in single scan g’~22 mag) of a narrow strip of sky each clear night in the Time Delayed Integration mode. A cadence of one day observation will provide unique opportunities to discover different types of supernovae (SNe) along with many other types of variable sources. We present the approach to discover SNe with the 4-m ILMT and discuss the follow-up strategy in the context of other existing observational facilities. The advantages of liquid mirror telescope observations over the traditional glass mirror telescopes are also discussed.

Polarization measurements are very helpful to understand the nature of some of the stellar and extra-galactic sources. Light from astronomical objects is in general polarized to some degree and its measurement gives additional information related to the magnetic field, the distribution of scattering material, the non-thermal nature of light, etc. Since the degree of polarization in the majority of astronomical sources is 1-5%, and polarimetry requires additional optics with respect to classical imaging, these measurements require much more photons to achieve a good signal-to-noise ratio for which the 3.6-m Devasthal Optical Telescope (DOT) facility is suitable.

Published: January 2022

We present the first period study of six contact binaries in the closest globular cluster M4 the data collected from June 1995−June 2009 and Oct 2012−Sept 2013. New times of minima are determined for all the six variables and eclipse timing (O-C) diagrams along with the quadratic fit are presented. For all the variables, the study of (O-C) variations reveals changes in the periods. In addition, the fundamental parameters for four of the contact binaries obtained using the Wilson-Devinney code (v2003) are presented. Planned observations of these binaries using the 3.6-m Devasthal Optical Telescope (DOT) and the 4-m International Liquid Mirror Telescope (ILMT) operated by the Aryabhatta Research Institute of Observational Sciences (ARIES; Nainital) can throw light on their evolutionary status from long term period variation studies.

We have generated a catalog of young stellar objects (YSOs) in the star forming region NGC 7538 using Ha and X-ray data. The spatial distribution of YSOs along with MIR, radio and CO emission are used to study the star formation process in the region. Our analysis shows that the 03V type high mass star 'IRS 6' might have triggered the formation of young low mass stars up to a radial distance of 3 pc.

We propose a study of interstellar molecules with near-infrared (NIR) high-resolution spectroscopy as a science case for the 3.6-m Devasthal Optical Telescope (DOT). In particular, we present the results obtained on-going survey of diffuse interstellar bands (DIBs) in NIR with the newly developed NIR high-resolution spectrograph WINERED, which offers a high sensitivity in the wavelength range of 0.91-1.36 µm. Using the WINERED spectrograph attached to the 1.3-m Araki telescope in Japan, we obtained high-quality spectra of a number of early-type stars in various environments, such as diffuse interstellar clouds, dark clouds and star-forming regions, to investigate the properties of NIR DIBs and constrain their carriers. As a result, we successfully identified about 50 new NIR DIBs, where only five fairly strong DIBs had been identified previously. Also, some properties of DIBs in the NIR are discussed to constrain the carriers of DIBs.

Galaxy mergers play a crucial role in the formation of massive galaxies and the buildup of their bulges. An important aspect of the merging process is the in-spiral of the supermassive black-holes (SMBHs) to the centre of the merger remnant and the eventual formation of a SMBH binary. If both the SMBHs are accreting they will form a dual or binary active galactic nucleus (DAGN). The final merger remnant is usually very bright and shows enhanced star formation. In this paper we summarise the current sample of DAGN from previous studies and describe methods that can be used to identify strong DAGN candidates from optical and spectroscopic surveys. These methods depend on the Doppler separation of the double peaked AGN emission lines, the nuclear velocity dispersion of the galaxies and their optical/UV colours. We describe two high resolution, radio observations of DAGN candidates that have been selected based on their double peaked optical emission lines (DPAGN). We also examine whether DAGN host galaxies have higher star formation rates (SFRs) compared to merging galaxies that do not appear to have DAGN. We find that the SFR is not higher for DAGN host galaxies. This suggests that the SFRs in DAGN host galaxies is due to the merging process itself and not related to the presence of two AGN in the system.

Narrow line Seyfert 1 (NLSy1) galaxies constitute a class of active galactic nuclei characterized by the full width at half maximum (FWHM) of the H broad emission line <2000 km s-1 and the flux ratio of [O III] to H <3. Their properties are not well understood since only a few NLSy1 galaxies were known earlier. We have studied various properties of NLSy1 galaxies using an enlarged sample and compared them with the conventional broad-line Seyfert 1 (BLSy1) galaxies. Both the sample of sources have z 0.8 and their optical spectra from SDSS-DR12 that are used to derive various physical parameters have a median signal to noise (S/N) ratio >10 pixel-1. A strong correlation between the H and Hα emission lines is found both in the FWHM and flux. The nuclear continuum luminosity is found to be strongly correlated with the luminosity of H, Hα and [O III] emission lines. The black hole mass in NLSy1 galaxies is lower compared to their broad line counterparts. Compared to BLSy1 galaxies, NLSy1 galaxies have a stronger FeII emission and a higher Eddington ratio that place them in the extreme upper right corner of the R4570 - λEdd diagram. The distribution of the radio-loudness parameter (R) in NLSy1 galaxies drops rapidly at R>10 compared to the BLSy1 galaxies that have powerful radio jets. The soft X-ray photon index in NLSy1 galaxies is on average higher (2.9 ± 0.9) than BLSy1 galaxies (2.4 ± 0.8). It is anti-correlated with the H width but correlated with the FeII strength. NLSy1 galaxies on average have a lower amplitude of optical variability compared to their broad lines counterparts. These results suggest Eddington ratio as the main parameter that drives optical variability in these sources.

Published: January 2022

Cette étude a pour objectif d’évaluer l’efficacité sur la dissolution des calculs biliaires de cholestérol in vitro d’une plante utilisée en médecine traditionnelle contre la lithiase vésicale; la mauve; Malva sylvestris L. préparée par infusion. Le pouvoir de dissolution de la mauve sylvestre vis-à-vis des calculs biliaires de type cholestérol a été évalué durant une période de huit semaines. La dissolution était signiﬁcative avec une perte moyenne de masse de 31,7 mg et de 21,49 mg concernant respectivement les calculs de poids faible et moyen à différents grossissements; par ailleurs, la perte était de 0,61 mg pour les calculs de haut poids. Une exposition plus longue pourrait se révéler efficace. De nouvelles expériences sont nécessaires pour confirmer cette hypothèse. Cependant, il paraît difficile aujourd’hui de recommander cette plante pour dissoudre des calculs de cholestérol in situ.
