Abstract River-flood forecasting is among the most important feasible non-structural approaches used in reducing economic losses and alleviating human sufferings. In spite of uncertainty in the forecasting of natural disasters, the current prevailing methods developed in many parts of the world in the recent history has made good progress to a great extent. The advancement is attributed mainly due to the availability of high-resolution weather data and the use of sophisticated computer modelling algorithms. However, it is desirable to conduct exploratory review studies to further improving the current state of affairs. The present paper reviews briefly the river-flood forecasting methods currently used worldwide with a specific focus in the context of the Kelantan River in Malaysia. Flooding in Malaysia is recurrent covering a large inhabited area compared with other natural disasters. Some of the popularly used methods in the literature such as statistical methods machine learning and methods based on chaos theory have been reviewed, The paper will also attempt to explore the future direction for research and development that might be useful specifically for dealing with the recurrent rivers flooding in Malaysia. A reasonably acceptable prediction of river streamflow is significantly important in disaster management and water resources management.

Low indoor air quality is an increasingly important problem due to the spread of urbanization. Because people spend most of their time inside, poor indoor air quality causes serious human health issues, resulting in significant economic losses. In this work, the current state of affairs is presented and analyzed, focusing on the current problems and the available solutions to improve the quality of indoor air, and the use of nature-based solutions. These involve the cultivation of microalgae in closed photobioreactors. In these systems, photosynthetic organisms can capture CO2 and other pollutants generated in indoor environments, which they use to grow and develop biomass. Several possible layouts for the implementation of microalgae-based indoor air cleaning systems are presented, taking into account the systems that are currently available at a commercial scale. A critical analysis of the microalgae indoor purification systems is presented, highlighting their advantages and disadvantages, and suggesting potential improvements and future lines of research and development in the area.

Post Humanism

The article analyzes the current state of affairs in philosophy in relation to the question «What is hu-man?». In this regard, the author identifies two strategies – post-humanism and post-cosmism. The strat-egy of post-humanism is to deny the idea of human exceptionalism. Humanity becomes something that can be thought of out of touch with human and understood as a right that extends to the non-human world. Post-cosmism, on the contrary, advocated the idea of ontological otherness of the human. Re-sponding to the challenges of anthropological catastrophe, its representatives propose a number of new anthropological projects.

Islamic Civilization

As an intellectual process, critical thinking plays a dynamic role in reconstructing human thought. In Islamic legal thought, this intellectual tool was pivotal in building a full-fledged jurisprudential system during the golden age of Islamic civilization. With the solidification of the science of Islamic legal theory and the entrenchment of classical Islamic jurisprudence, this process abated somewhat. Recent Islamic revival movements have engendered a great zeal for reinstituting this process. The current state of affairs in constructing and reconstructing Islamic jurisprudence by and large do not, however, reflect the dynamic feature of intellectual thought in this particular discipline. Thus this article attempts to briefly delineate this concept, unveil the reality on the ground, and identify some hands-on strategies for applying critical thinking in contemporary ijtihad.

Pakistan remains a country of vital importance for Al-Qaeda. It is primarily because of Al-Qaeda’s advent, rise and shelter and not to mention the support the terrorist organization found at the landscape of Pakistan during the last two decades. The emergence of in Pakistan can be traced back to the Afghan War (1979-89), with a brief sabbatical in Sudan the Islamist terrorist group rose to gain prominence after shifting back to Afghanistan. It then became a global ‘Islamist’ terrorist entity while based in neighboring Afghanistan and found safe havens in the erstwhile tribal areas of Pakistan in the aftermath of the US invasion of Afghanistan in 2001. Prior to its formation in 1988 in Peshawar (Pakistan), it had worked as Maktab al-Khidmat (Services Bureau) during the Afghan War.2 It had its roots in Pakistan, which had become a transit point of extremists en route to Afghanistan during the War. All high profile Al-Qaeda leaders, later becoming high-value targets, and members of its central Shura had lived in Pakistan at one point in their lives. That is the very reason the Al-Qaeda in Pakistan is termed as Al-Qaeda Core or Central among law enforcement practitioners and intelligence communities. Without going into details of Al-Qaeda’s past in Pakistan the aim of this article is to focus on its current state of affairs and what future lies ahead of it in Pakistan.

Background: image forensics deal with the problem of authentication of pictures or their origins. There are two types of forensics techniques namely active and passive. Passive forgery is also known as blind forensics technique. In passive forgery, copy-move (cloning) image forensics is most common forgery technique. In this approach, an object or region of a picture is copied and positioned somewhere else in the same image. Active method used watermarking to solve picture genuineness problem. It has limitations like human involvement or particularly equipped cameras. To overwhelm these limitations, numerous passive authentication approaches have been developed. Moreover, both approaches do not require any prior information about the picture. Objective: The prime objective of this survey is to provide an inclusive summary as well as recent advancement, challenges and future direction in image forensics. In Today’s digital era the digital pictures and videos are having great impact on our life as well as society, as they became the important source of information. Though earlier it was very difficult to doctor the picture, nowadays digital pictures can be doctored easily with the help of editing tools and internet. These practices make pictures as well as videos genuineness deceptive. Conclusion: This paper presents the current state-of- the-art of passive (cloning) image forensics techniques, challenges and future direction of this research domain. Further, the major open issues in developing a robust cloning image forensics detector with their performance are discussed. Lastly, the available benchmark datasets are also discussed

In recent years, a continuous decline of ice-coverage in the Arctic has been recorded, but these high latitudes are still dominated by earth’s polar ice cap. Therefore, safe and sustainable shipping operations in this still frozen region have as a precondition the availability of ice-breaking support. The analysis in hand provides an assessment of the United States’ and Canada’s polar ice-breaking program with the purpose of examining to what extent these countries’ relevant resources are able to meet the facilitated growth of industrial interests in the High North. This assessment will specifically focus on the maritime transportation sector along the Northwest Passage and consists of four main sections. The first provides a very brief description of the main Arctic passages. The second section specifically explores the current situation of the Northwest Passage, including the relevant navigational challenges, lack of infrastructure, available routes that may be used for transit, potential choke points, and current state of vessel activity along these routes. The third one examines the economic viability of the Northwest Passage compared to that of the Panama Canal; the fourth and final section is investigating the current and future capabilities of the United States’ and Canada’s ice-breaking fleet. Unfortunately, both countries were found to be lacking the necessary assets with ice-breaking capabilities and will need to accelerate their efforts in order to effectively respond to the growing needs of the Arctic. The total number of available ice-breaking assets is impacting negatively the level of support by the marine transportation system of both the United States and Canada; these two countries are facing the possibility to be unable to effectively meet the expected future needs because of the lengthy acquisition and production process required for new ice-breaking fleets.

In Chile and Ecuador, multiple hazards and dynamic processes in vulnerability pose a high risk. Spatial planning and emergency management can contribute to disaster risk management but they follow different goals. However, global goals, such as from UN-ISDR (United Nations International Strategy for Disaster Risk Reduction) and UN SDGs (Sustainable Development Goals) can potentially support cities and regions in defining concerted action. This paper aims at measuring the performance of Chile and Ecuador in regard to the aforementioned policy goals. Although both countries show considerable progresses in the implementation of the UN strategies, it is doubtful that the existing global monitoring approach is appropriately designed for measuring the real situation on the ground. Our paper is based on a desktop research combined with stakeholder workshops and expert interviews. Overall, both countries made considerable progress in regard to disaster preparedness and monitoring. However, multi-risks are rarely considered and there is still increasing vulnerability due to the expansion of informal settlements. The risk management is characterized by an imbalanced distribution of financial resources and institutional capacities between the metropolitan regions and smaller municipalities, and by low public participation and hardly community-based approaches. The paper underlines the importance for more qualitative, in-depth studies on the root causes of disaster risk which could complement the global monitoring which is very much focused on quantitative data and shows inconsistency between input and output indicators.
