Route planning of automated guided vehicles for container logistics

Automated guided vehicles (AGVs) are widely used in container terminals for the movement of material from shipping to the yard area and vice versa. Research in this area is directed toward the development of a path layout design and routing algorithms for container movement. The problem is to design a path layout and a routing algorithm that will route the AGVs along the bi-directional path so that the distance traveled will be minimized. This thesis presents a bi-directional path flow layout and a routing algorithm that guarantee conflict-free, shortest time routes for AGVs. Based on the path layout, a routing algorithm and sufficient, but necessary conditions, mathematical relationships are developed among certain key parameters of vehicle and path. A high degree of concurrency is achieved in the vehicle movement. The routing efficiency is analyzed in terms of the distance traveled and the time required for AGVs to complete all pickup and drop-off jobs. Numerical results are presented to compare performance of the proposed model. The research provides the foundation for a bi-directional path layout design and routing algorithms that will aid the designer to develop complicated path layouts

Investigating Heterogeneous Nucleation of Barite using Hydrothermal Atomic Force Microscopy and Optical Microscopy

In order to develop a better understanding heterogeneous nucleation of barite, barite precipitation was studied under varying experimental parameters. Hydrothermal atomic force microscopy (HAFM) and optical microscopy were used to investigate the effect of change in temperature, supersaturation and varying ratios of ions on heterogeneous nucleation of barite. In the experiments conducted at higher temperatures, the particles thus nucleated were found to display characteristic hexagonal and rhomboidal shapes. In comparing results of particle densities among different ion ratios, there is evidence suggesting that barium to sulfate ratio plays a role of promoter. Wherein, the ratios with higher [Ba2+] concentration were found to show more nucleation occurring. Although, the HAFM cell was used for experimentation, optical microscopy turned out to be a more effective method for analysis of samples

Dynamic Analysis of Bridges Under Moving Loads

Moving loads have great effect on dynamic stresses in structures and cause them to vibrate extensively, especially at high velocities. A peculiar feature of moving loads is that they are variable in both space and time. This is why the dynamic analysis of bridges under moving forces has attracted researchers worldwide. When a moving load is traveling on a bridge, different factors play an important role in the vibration of the bridge. Road surface profile, vehicle dynamics, weight and speed of the moving vehicle and the geometry of the bridge all play an important roles in the analysis. The main objective of this research work is to study the collective effect of all these factors over the impact factor. Road surface roughness is generated by using a Power Spectral Density function which represents different classes of roads. A 12 Degree Of Freedom model of an HS20- 44 truck is modeled and an interactive function of this model with the road surface roughness is developed to find an increased load which is applied on the bridge decks to find the dynamic response. The bridge deck is analyzed by using analytical and numerical methods. An orthotropic plate theory is used to solve the bridge deck analytically and the finite element analysis method is used to solve the bridge numerically. The increased load calculated from the interaction function of road surface roughness and vehicle model is simulated as a train of moving loads by using Dirac-delta function in the orthotropic plate theory. The same train of moving loads is simulated in finite element analysis by using arrival time and time function data for the nodal points along the moving path of the truck load. Dynamic response is calculated in terms of the vertical deflection at the center of the bridge deck and compared with the static deflection where the load is considered to be steady. For the bridge deck under investigation, the impact factor given by AASHTO underestimates the dynamic effect under the moving loads. This might be because of the inability o f the impact factor formula given by AASHTO, which is a function of span length of the bridge deck, to take into account the effect of road surface roughness, vehicle dynamics, vehicle weight, and vehicle speeds. Its is suggested that it is necessary to do the detailed dynamic analysis of bridges by considering road surface roughess, vehicle dynamics, vehicle weight, and vehicle speed

A Case Report on Ayurvedic Management of Attention Deficit Hyperactivity Disorder [ADHD] in Children

Attention Deficit Hyperactivity Disorder - ADHD is the most common neurobehavioral disorder of childhood. It interferes with social, academic and occupational functioning and it is characterized by in-attention, hyperactivity and impulsivity. In Ayurveda, disorders related to psychiatric and behavioral disturbances are discussed under the chapter of Unmada. So, according to the sign and symptoms it can be co-related with Unmada. The present case was carried out in Kaumarabhritya OPD & IPD of Government Ayurveda Medical College & Teaching Hospital, Shivamogga, Karnataka with an aim to assess the efficacy of Ayurvedic treatment protocol in the management of ADHD in children. Ayurvedic treatment like Kosthashodhana, Basti, Shirodhara and Nasya were followed and assessment was done before and after treatment and during follow ups. The given treatment was found to be effective in management of ADHD

Quantitative Estimation of Mangroves and Their Associates’ Marshy Lands at Palghar District in Maharashtra

Mangroves are the shrubs or trees growing in coastal saline or brackish water. The ecological study has practical applications in conservation biology, wetland management, natural resource management, city planning community health economic, basic & applied science & human social interaction. Mangrove ecosystems are highly productive but extremely sensitive and fragile. The present study deals with quantitative estimation, density, abundance and diversity index of mangroves located in western coastal region of Maharashtra, the Palghar district which is also a part of Konkan tract or Konkan coast. In the study area of Palghar coastline, out of 16 recorded species, 13 species are true mangrove from 4 genera & 8 families are observed. The flora from family Acanthaceae, Primulaceae, Fabaceae, Convolvulaceae, Combretaceae, Rhizophoraceae, Salvadoraceae, Aizoaceae, Lythraceae, Amaranthaceae are recorded as mangroves and their associates at 5 marshy locations of Palghar coastlines. Due to anthropogenic activity, industrialization & tourisms, sewage water and non-degradable wastes like plastic wrappers, plastic bottles get deposited in the marshy areas which is the reason why the mangrove are degraded. The covered upline areas with plastic suffocate the roots, even the pneumatophores and plants die due to suffocation. Until the adaptation for the plastic-coated marshy lands has not been developed in mangrove plants
