Machine learning based identification of digitally modulated signals
The automatic identification of the modulation type of a signal at the receiver is a major task of an intelligent receiver, such as software defined radio (SDR), which is used in different communication systems. With no knowledge of the transmitted data, recognition of the modulation type is a difficult task. A communication system, in which receiver is designed based on Machine learning is trained to detect the message using statistical parameters. In this work, machine learning algorithm is developed for identifying 6 different modulated signal types at the receiving end. MATLAB tool is used to generate different modulated signals. Identification of modulation type is done by analyzing different statistical features such as normalized PSD, kurtosis and sum-fft which are calculated using the sampled version of received signal. The algorithm is tested for different frequency and amplitude signals at the receiving end and results are tested for correctness.

Measurements of Indoor Radon-222 Concentration inside Iraqi Kurdistan: Case Study in the Summer Season
Exposure to natural sources of radiation, especially 222Rn and its short-lived daughter products has become an important issue throughout the world because sustained exposure of humans to indoor radon may cause lung cancer. Therefore, indoor radon concentration levels have been measured inside 8 government hospitals in three main regions (Erbil, Duhok and Sulaymaniya) in Iraqi Kurdistan region during summer season by using CR-39 nuclear track detector. The CR-39 detectors were placed in the all hospitals for three floors (ground, first and second). The highest average radon concentration value and annual effective dose was found to be in the Shaheed Dr.Aso hospital in Sulaymaniya city (52.89±3.52 Bq.m-3 , 1.37±0.09 mSv/y ) respectively and the lowest was found in the Erbil Teaching hospital in Erbil city (30.15±2.85 Bq.m-3 , 0.81 mSv/y) respectively, This depended on the geological formation , type of building material, and the floor level. Therefore, the results showed that the average radon concentration and annual effective dose decreases gradually as the floor level increases The highest and lowest of annual effective dose was found in ground and second floor, respectively. Thus, according to the annual exposure dose data, the workers are safety in most of the hospitals.

Measuring Entrepreneurial Orientation towards Health Care Sector in Kerala, India
This paper focuses on the skills, characteristics and personality traits of owner’s managers. Many countries are working on the realization of a new sort of public management, which is less governmental and more market oriented. As a consequence the role of health-care managers is changing. They are increasingly addressed as (social) entrepreneurs. This article is based on the results of a survey sent to health-care executives in Kerala,India.The aim of the survey was to explore how the new discourse affects the practice of management. The results show that entrepreneurship is a construction and a contested concept. Nevertheless, executives are very sensitive to the concept. It certainly confuses them and can make them feel more vulnerable. However, new expectations can also perform an important function as a catalyst for executives to rethink their role and their position. From that point of view the phase of multiinterpretable expectations and vague discourse can be seen as a necessary phase in realizing health-care reform.

Mindfulness and Psychological Flexibility as Predictors of Burnout in Healthcare Workers: A Comparative Gender-Based Study
Healthcare workers are particularly concerned about burnout, which is characterised by depersonalization (DP), emotional exhaustion (EE), and decreased personal accomplishment (PA). Among 160 healthcare workers in Odisha, India, this study examined the predictive functions of psychological flexibility and mindfulness in connection to burnout. Multiple regression analysis, two-way ANOVA, Pearson’s correlation, and descriptive statistics were used to analyse the data. Mindfulness showed a positive correlation with PA (r = 0.44, p <.01) and a negative correlation with EE (r = -0.56, p <.01) and DP (r = -0.47, p <.01). Psychological flexibility showed a positive correlation with PA (r = 0.37, p <.01) and a negative correlation with EE (r = -0.49, p <.01) and DP (r = -0.41, p <.01). Regression studies showed that psychological flexibility (B = -0.64, ? = -0.36, t = -5.79, p <.001) and mindfulness (B = -0.48, ? = -0.41, t = -6.78, p <.001) were significant predictors of burnout. Main effects of gender on EE (F (1,156) = 6.84, p =.01) and DP (F (1,156) = 5.92, p =.02) were found by two-way ANOVA. Additionally, a gender × psychological flexibility interaction on EE was found (F (1,156) = 4.77, p =.03). Males reported higher DP, whereas females reported higher EE. The results support mindfulness and flexibility-based therapies in healthcare and highlight the value of psychological resources in lowering burnout.

Modeling of a multifunction family Kiln prototype for biochar production and energy valorization
Excessive wood consumption in Burkina Faso has led not only to deforestation, but also to soil degradation. The preservation of ecosystem balances, the management of soil fertility and the safeguarding of forests are major issues for future generations. It is in this context that our work has focused on the development of an energy conversion technology that effectively uses little-used agricultural residues (cotton stalks, bare corn cobs, rice husks, etc.). This device is a multifunction family furnace that produces biochar for soil amendment and provides alternative energy for household needs. The physical and mathematical modeling of the oven based on the nodal method whose equations were solved by implicit finite differences allowed to describe its thermal behavior. K-type thermocouples were used for the experimental study to validate the mathematical model. Indeed, the pyrolysis temperature of the bare corn cobs is on average 450 °C. The model allowed us to show that the thickness of the pyrolysis chamber influences the pyrolysis temperature and reduces the pyrolysis time. For a thickness of 8 cm of the pyrolysis chamber, the average pyrolysis time is 1 hour 30 minutes. The study also showed that the variation of the ambient temperature does not influence the pyrolysis temperature. Moreover, the thickness of the insulation chamber affects the external wall temperature but not the pyrolysis temperature.
