A Radio-fingerprinting-based Vehicle Classification System for Intelligent Traffic Control in Smart Cities

The measurement and provision of precise and upto-date traffic-related key performance indicators is a key element and crucial factor for intelligent traffic controls systems in upcoming smart cities. The street network is considered as a highly-dynamic Cyber Physical System (CPS) where measured information forms the foundation for dynamic control methods aiming to optimize the overall system state. Apart from global system parameters like traffic flow and density, specific data such as velocity of individual vehicles as well as vehicle type information can be leveraged for highly sophisticated traffic control methods like dynamic type-specific lane assignments. Consequently, solutions for acquiring these kinds of information are required and have to comply with strict requirements ranging from accuracy over cost-efficiency to privacy preservation. In this paper, we present a system for classifying vehicles based on their radio-fingerprint. In contrast to other approaches, the proposed system is able to provide real-time capable and precise vehicle classification as well as cost-efficient installation and maintenance, privacy preservation and weather independence. The system performance in terms of accuracy and resource-efficiency is evaluated in the field using comprehensive measurements. Using a machine learning based approach, the resulting success ratio for classifying cars and trucks is above 99%

Measurement and comparison of Iron levels and hazard quotient (HQ) on muscle of farmed and marine fishes from Khuzestan, south west of Iran

The aim of this study was to determine the concentration of iron and Hazard quotient (HQ) in muscle of four marine fishes, orange - spotted grouper (Epinephelus coioides), yellow fin sea bream (Acanthopagrus latus), tongue fishes (Cynoglossus arel), silver pomfret (Pampus argenteus) and farmed carp fish, common carp(Cyprinus carpio), grass carp (Ctenopharyngodon idella), big head carp (Aristichthys nobilis) and silver carp (Hypophthalmichthys molitrix) from Khuzestan. Farmed fish sample was prepared from the Azadegan warm water fish culture center and marine fish was prepared from fishing ports Bahrkan, Abadan and Bandar Emam. Iron concentration measured by wet digestion and atomic absorption spectrometer Perkin Elmer 4100.The results showed the average of iron level in farmed fish was 17.08± 1.21 mg/kg dry weight and in marine fish was 10.68± 3.66 mg/kg dry weight (p<0.05).The results showed that the highest iron concentrations between farmed fish muscle was on big head carp equal to 18.16mg/kg dry weight and was significantly different (p<0.05) with grass carp and the highest iron concentrations between marine fish muscle was onTongue fishequal to 15.50± 0.50mg/kg dry weight and was significantly different (p<0.05). Average hazard quotient in farmed fish was HQ=0.61and in marine fish was HQ =0.38. Hazard quotientin marine fish were in tongue fish HQ=0.55, yellow fin sea breamHQ =0. 3, Orange - spotted grouper HQ= 0.26 and silver pomfret HQ =0.41 and Hazard quotient in fish were in big head HQ=0.65, common carp HQ =0.63 grass carp HQ= 0.55and silver carp HQ =0.61. Hazard quotient in all samples was less than one and so fish nutrition no risk in terms of the amount of iron in the human body

Accumulation variations of selected heavy metals in Barbus xanthopterus in Karoon and Dez Rivers of Khuzestan, Iran

The concentrations of Cd, Pb, Ni and Hg were determined in gill, liver and muscle of Barbus xanthopterus in down streams of Karoon and Dez Rivers during summer 2009. Heavy metal concentrations varied significantly, depending on the types of the tissue in fish species. The levels of heavy metals such as Cd, Pb, Ni and Hg in the Barbus xanthopterus of Karoon River were higher than in Barbus xanthopterus of Dez River (Pliver>muscle. The concentration of Hg in Karoon River was in the sequence liver>gill>muscle but, in Dez River, it was in the sequence liver>muscle>gill. Among heavy metals (Cd, Pb, Ni and Hg), the accumulation of Pb was more than other heavy metals in fish (P<0.05). In both rivers, the accumulation of heavy metals in muscle of fish was higher than the world health organization (WHO) standard

Interactive effects of diet protein and water salinity on growth and survival of white leg shrimp (Litopenaeus vannamei Boone 1931)

This study was conducted in the Shrimp Research Center of Bushehr in winter 2005. We treated reared White Leg Shrimp (Litopenaeus vannamei Boone 1931) with five diets containing 20%, 25% ,30%, 35% and 40% protein levels and three salinity levels 15-17ppt, 27-30ppt, and 40-45ppt. We focused on growth, survival, food conversion ratio, hemolymph osmolality, hemolymph protein and corpse protein content. We applied 15 treatments each with three replicates in 45 tanks with 300 liter capacity. Shrimps average weight was about 2 grams at the start and reared after 60 days of culture. Shrimp biomass growth in 15-17 salinity was higher than other salinities showing statistically significant difference with those grew in 40-45ppt salinity (P>0.05). No statistically significant difference was found between growth of the shrimp in 15-17ppt and in 27-30ppt water

Radio-based Traffic Flow Detection and Vehicle Classification for Future Smart Cities

Intelligent Transportation Systems (ITSs) providing vehicle-related statistical data are one of the key components for future smart cities. In this context, knowledge about the current traffic flow is used for travel time reduction and proactive jam avoidance by intelligent traffic control mechanisms. In addition, the monitoring and classification of vehicles can be used in the field of smart parking systems. The required data is measured using networks with a wide range of sensors. Nevertheless, in the context of smart cities no existing solution for traffic flow detection and vehicle classification is able to guarantee high classification accuracy, low deployment and maintenance costs, low power consumption and a weather-independent operation while respecting privacy. In this paper, we propose a radiobased approach for traffic flow detection and vehicle classification using signal attenuation measurements and machine learning algorithms. The results of comprehensive measurements in the field prove its high classification success rate of about 99%

A comparative study was conducted on concentration of heavy metals including: Hg, Cd and Pb in the muscle of Otolithes ruber in Abadan and Bandar Abbas Ports in the Persian Gulf. In this study, a total of 42 specimens of Otolithes ruber were collected from coastal waters of Abadan and Bandar Abbas Ports in 2010. Heavy metals were extracted from the muscle tissues using wet digestion method and concentration of metals were measured by Atomic Absorption Spectrophotometer. The results showed that mean (±SD) accumulation of Hg, Cd and Pb in the muscles of Otolithes ruber in Bandar Abbas were 0.058±0.001, 0.279±0.056 and 0.668±0.077mgKg-1 wet weight, and in Abadan were 0.056±0.007, 0.25±0.038 and 0.638±0.087mgKg-1 wet weight respectively. No significant differences were found in concentrations of Hg, Cd and Pb in the muscle of Otolithes ruber between Abadan and Bandar Abbas ports. Accumulation of these metals were higher in the muscle of Otolithes ruber than that Bandar Abbas Port. Concentration of Hg in the muscle of Otolithes ruber was lower than acceptable limit suggested by WHO, MAFF, NHMRC. However concentrations of Pb and Cd were higher

In situ readout of DNA barcodes and single base edits facilitated by in vitro transcription

Molecular barcoding technologies that uniquely identify single cells are hampered by limitations in barcode measurement. Readout by sequencing does not preserve the spatial organization of cells in tissues, whereas imaging methods preserve spatial structure but are less sensitive to barcode sequence. Here we introduce a system for image-based readout of short (20-base-pair) DNA barcodes. In this system, called Zombie, phage RNA polymerases transcribe engineered barcodes in fixed cells. The resulting RNA is subsequently detected by fluorescent in situ hybridization. Using competing match and mismatch probes, Zombie can accurately discriminate single-nucleotide differences in the barcodes. This method allows in situ readout of dense combinatorial barcode libraries and single-base mutations produced by CRISPR base editors without requiring barcode expression in live cells. Zombie functions across diverse contexts, including cell culture, chick embryos and adult mouse brain tissue. The ability to sensitively read out compact and diverse DNA barcodes by imaging will facilitate a broad range of barcoding and genomic recording strategies
