Relationship between morphometric stream characteristics and sediment heavy metal pollution in a mining-influenced watershed

Streams located in watershed environments act as a principal component of transportation and reservoir of heavy metals evacuated by mining activities. This study evaluated the relationship between morphometric stream characteristics and variations in the rate of sediment heavy metal pollution in a mining-influenced watershed. The study area was a mining site located in the Anguran region, Zanjan province, Iran. Three rivers were selected that exhibited significant differences in terms of path length and slope. Approximately 1500 g sediment was collected from downstream positions of Kaka River (R1), Allah Lochay River (R2), and Shurab River (R3). Total zinc (Zn), nickel (Ni), lead (Pb), and cadmium (Cd) concentrations and particle size distribution were measured. The pollution load index (PLI) and geo-Accumulation Index (Igeo) were then calculated. Based on the results, the sediment particle size distribution significantly decreased in response to an increase in the river length and slope (R1>R2>R3). Stream path length and slope are factors determining the size of bed particles transported by a river. The streams with longer path lengths and steeper slopes could transport finer fractions toward depositional positions. Further, the pollution level of the Kaka River sediment was the highest compared with other rivers. The highest Igeo value for the measured heavy metals was also observed in the Kaka River sediment, followed by the sediments of Allah Luchay and Shurab rivers. The regression results illustrated that the heavy metal concentrations were significantly positively correlated with clay and silt contents. These findings unequivocally showed that watershed environments exhibit a high vulnerability to mining activities because the streams can facilitate the transportation of sediment polluted by heavy metals across the landscape. On the other hand, the streams with higher length and slope surrounding mining sites increase the pollution transfer rate and cause a higher level of sediment heavy metal pollution.
Automated Traffic Control for Rescue Vehicles

Because of the population boom, there is an exponential rise in the number of physical objects or vehicles on the road. As a result of the increased traffic volume, the number of road accidents rises. In this article, traffic flow is controlled using a computer vision paradigm, in which images or a series of images improves the road view. This research work employs the camera module of the Raspberry Pi along with the Raspberry Pi 3 to detect cars, track, and estimate traffic flow using low-cost electronic devices. It also intends to create a remote access system based on the Raspberry Pi that will identify, track, and count vehicles only when certain variations occur in the monitored region. The proposed system collects video streams such as vehicles in the monitored region in order to compute information and transmit the compressed video stream in order to provide a videobased solution, which is primarily implemented in Open CV using Python programming. The proposed method is considered as an economical solution for industries in which cost-effective solutions are developed for traffic management.I.

A Multi-granularity Targeted Covert Collection Scheme for Internet Data

The targeted covert collection of Internet data, which can not only effectively hide users' traces but also efficiently navigate to target data, plays an important role in three-dimensional social security. Due to big data generated by online social networks, large-scale network analysis usually confront with unbearable computational complexity, resulting in failing to achieve expected results within the specified response time. To retrieve and analyze the most important data within predetermined time, we study the problem of targeted covert collection with multiple granularity levels for Internet data in this paper. To find target data (or web users interchangeably), we use a tree indexes with the largest spanning tree to rank Internet data. Finally, we propose an effective collect algorithm for Internet data acquisition under different granularity levels. We validate our proposed scheme with the real data, which are gathered from the an online social platform. The experiment results verify that our algorithm can find the target data and collect data covertly with different granularity levels.
Entropy-Based Quantification of Privacy Attained Through User Profile Similarity

Location-based services refer to services that use location as primary input. But accessing user's location by an adversary invites issues of privacy breach. Instead of specific location coordinates, its surrounding area known as cloaking region is revealed in order to get the service. K anonymity technique of location privacy ensures that at least K-1 users should be included within a specific cloaked region. Researches have established that on combining K anonymity with the idea of including similar users together in a cloaked region provides stringent privacy (especially from background and heterogeneity attacks). This work quantifies the amount of privacy gain attained through, opting-for users with similar profiles instead of random users. The quantification is done by using KL divergence. Values of KL divergence of user profiles have been calculated for different cloaking regions containing similar and random users. Low KL divergence values depict privacy gains up to 33% for users with similar profiles.

Designing Software Systems That Age Well and Adapt to Change

Building systems that are as easy to understand and maintain in year five as they were in year one does not happen naturally. It takes deliberate and disciplined effort, along with a firm grasp of the reasons, to understand why systems become difficult to change. This resistance to change is known as software entropy, which is the natural tendency of software to devolve toward disorder and chaos. In this chapter, we will focus on what it takes to design, build, and maintain systems that age well and can adapt to change over the lifetime of the project.

Tamil Character Recognition in Palm Leaf Manuscripts

Tamil characters are of historical significance. The shapes of the character and its writing continued to be changed by several reformers in each century until the period of the nineteenth century. The Tamil characters in the palm leaf manuscripts are based on the author's writing style and strokes in use at the time. Reading palm leaf manuscripts is a challenge for the modern generation who are unaware of the character strokes and writing patterns written in earlier times, and the younger generation neglects to read and understand the contents written in palm leaf manuscripts. To read Tamil palm leaf manuscripts it is necessary to remember the shapes of the character that has changed over time and to compare and recognize the characters. This research paper explains how to recognize the Tamil characters written in palm leaf manuscripts by computer. By this research, the Tamil characters can be compared with different strokes and shapes and the exact character can be recognized accurately and quickly.

This paper uses Django framework based on MVC mode, mongodb with distributed storage and jQuery EasyUI as background management subsystem to develop a complete English online teaching system. This paper focuses on the ways and methods of strengthening cultural factors and improving learners' intercultural communicative competence in the new teaching mode. Experiments show that this method can improve the effectiveness of English classroom teaching.
Lossless Data Hiding in LWE-Encrypted Domains Based on Key-Switching

This paper proposes a lossless data hiding scheme in learning with errors (LWE)-encrypted domain based on key-switching technique. Lossless data hiding and extraction could be realized by a third party without knowing the private key for decryption. Key-switching-based least-significant-bit (KSLSB) data hiding method has been designed during the lossless data hiding process. The owner of the plaintext first encrypts the plaintext by using LWE encryption and uploads ciphertext to a (trusted or untrusted) third server. Then the server performs KSLSB to obtain a marked ciphertext. To enable the third party to manage ciphertext flexibly and keep the plaintext secret, the embedded data can be extracted from the marked ciphertext without using the private key of LWE encryption in the proposed scheme. Experimental results demonstrate that data hiding would not compromise the security of LWE encryption, and the embedding rate is 1 bit per bit of plaintext without introducing any loss into the directly decrypted result.
