However, travel demand modeling (TDM) is an essential input for urban transportation planning. TDM needs to be highly precise and accurate by integrating the accurate base year estimation along with suitable alternatives. Currently, activity-based models (ABMs) have been developed mostly for large metropolitan planning organizations (MPO), whereas smaller/medium-sized MPOs typically lack these models. The main reason for this disparity in ABM development is the complexity of the models and the cost and data requirements needed. We posit however that smaller MPOs could develop ABMs from traditional travel surveys. Therefore, the specific aim of this paper is to develop a probabilistic home-based destination activity trip generation model considering travel time behavior. Results show that the developed model can significantly capture the actual number of trip generations.

To communicate between these devices a number of protocols have been developed-Bluetooth and IEEE 802.11 being two dominating protocols. For developing applications on these mobile devices, we need good support for device discovery and at the same time protocol independent consistent application programming interface (API) which will make the job of application developers easier. Keeping application developers free from worrying about underlying communication protocols and at the same time ensuring application portability across protocols is a major design issue in current generation middleware for ubiquitous computing. In this paper, we present a device discovery service in the middleware for ubiquitous computing-MARKS, that also provides a consistent API for application development hiding the underlying communication protocols from application developers.

As a result, the current research was carried out in order to collect data for a database of minor fruit composition. The antioxidant activity of 1,1-diphenyl-2picryl hydrazyl (DPPH) scavenging and reducing power assays were used to evaluate the total phenolic (TPH), vitamin C, total carotene, and s-carotene contents and antioxidant activity of selected minor fruits (RPA). High-performance liquid chromatography with a photodiode array detector and autosampler was used to analyse phenolic compounds. The findings revealed that minor fruits contain a variety of phytochemicals,, particularly TPH, ascorbic acid, total flavonoid (TF), s-carotene, total carotenoid (TC), and total anthocyanin content (TAC); values ranged, respectively, 0.23-176.50 mg GAE/g, 16.67-664.92 mg/100 g, 2.26-150.02 mg QE/100 g, 1.41-6897.57 µg/100 g, 1.26-98.24 mg/100 g and 1.15-47.46 mg/100 g. In the parameters antioxidant activity, total antioxidant capacity, DPPH, reducing power capacity (RPC), ferric reducing antioxidant power (FRAP), metal chelating capacity (MCC), nitric oxide (NO), and free radical scavenging activity, IC50 ranged 0.01-278.24 µg of ascorbic acid/mg of extract, 39.70-250.00%, 3.21-634.00%, 0.02-1817.88 µM Fe2SO4/100g, 22.29-210.43%, 0.02-70.50%, and 4.98-856.70 µg/g, respectively. Phenolic acids that have been found and quantified, leading examples were gallic acid (279.06 mg/100 g), vanilic acid (43.77 mg/100 g), Þ-courmaric acid (178.96 mg/100 g), ferulic acid (20.44 mg/100 g), and lutein (91.13 µg/100 g) in aonla, day fruit, elephant apple, and bilimbi.

Correlation and path analysis was executed in twentythree tomato genotypes for thirteen yield contributing characters. The correlation coefficients were ascertained to detect the studied character interrelationships. Yield (t/ha) was showed positive and highly significant correlated with yield per plant(r =0.99) followed by individual fruit weight (r =0.72), fruit breadth (r =0.67), number of locules per fruit (r =0.67) and pericarp thickness (r =0.66) which indicated that yield could be enhanced by improving these traits. Path coefficient analysis indicated the cause and effect relationship among yield (t/ha) and its components. Yield per plant exhibited the highest positive direct effect (1.018) on yield (t/ha) followed by the number of flowers per inflorescence (0.212) and pericarp thickness (0.155). Fruit breadth (-0.279) showed the highest negative direct effect on yield (t/ha) but it had a highly significant positive correlation with Yield (t/ha) (r=0.67). High direct effect on yield (t/ha) was revealed by the characters that indicated direct selection in favor of these traits might be feasible. Selection based on these characters has great potential for improving yield (t/ha). The studied characters explained almost all variability towards yield signified by considerably very low residual effect (0.004606).

Half of each treatment was kept at (6±1°C and 50±5% RH) and the other half was kept at ambient conditions (25±3°C and 60±5% RH). LDPE bag or PE cling film has a great effect to retain firmness and reduce weight loss of cauliflower in both storage conditions. Respiration rate, rot incidence and changes of colour values (lightness and hue angle) was reduced significantly for the cauliflowers packed in LDPE bag or wrapped with PE cling film stored in a refrigerator than that of control (without packaging) and all packaging techniques stored at ambient condition throughout the storage period. Initially, acidity, TSS and ascorbic acid content were 0.26%, 4.7° Brix and 58.7 mg 100g-1 , respectively. Ascorbic acid content was reduced severely in the cauliflower stored in ambient conditions than that stored in a refrigerator. Cauliflower wrapped with PE cling film and packed in an LDPE bag (1% perforation) stored in a refrigerator (6±1°C and 50±5% RH) could retain white colour, good sensory quality, firm and fresh curds with minimum loss in weight, texture and disease incidence up to 18 days and 16 days, respectively.

This experiment was carried out to increase the shelf life and maintaining the quality of mango (... more This experiment was carried out to increase the shelf life and maintaining the quality of mango (Mangifera indica) fruits. There were two factors. Factor A: postharvest treatments with six levels (1. untreated (control), 2. washing with chlorine, 3. dipping (5 minutes) in calcium chloride (CaCl 2), 4. dipping (5 minutes) in bavistin and rinse in clean water, 5. hot water treatment and 6. tap water wash) and factor B: packaging technique with five levels (1. without packaging (control), 2. perforated poly bag (0.5%), 3. non-perforated poly bag, 4. plastic crate and 5. corrugated fibre board carton). The fruits treated with chlorine wash, tap water wash, hot water treatment, dipping in calcium chloride and bavistin were significant difference on chemical parameter (total sugar content, vitamin-C, total titrable acidity and total soluble solid) of mango. Treated fruits performed less disease incidence compared to without treated fruits. Non-treated fruits were attacked by the sunken black spots on the surface of the fruits as well as anthracnose (Colletotrichum gloeosporioides). In case of packaging technique, fruits packed in different packaging materials (like corrugated fibre board carton, plastic crate, perforate and non-perforated polyethylene bag) had the maximum shelf life, lower physiological loss in weight and less disease incidence than without package. Among the different packaging materials, fruits packed in corrugated fibre board carton had the maximum shelf life (13.02 days), lower physiological loss in weight (4.11%) and less disease incidence (1.12%) without excessive deterioration compared to others. The shelf life of mango could be extended up to 5 days by hot water treatment and packed in. corrugated fibre board carton compared to others. The color and quality of mango was very better in treated fruits compared to non-treated fruits.

Following treatment, fresh-cut carrot slices were kept in a polypropylene (PP) box and stored in a refrigerator (4±1°C and 50±5% RH) for 12 days. The effectiveness of the treatments in extending shelf life was evaluated by determining respiration rate, firmness, weight loss, external colour, whiteness index (WI), some chemical parameters (ascorbic acid content, TSS, acidity, pH, total sugar, reducing sugar and beta carotene), total bacterial count (TBC) and sensory quality. The highest increment of WI (48.4%) was observed without heattreated carrot slices. On the other hand, WI was increased by 12.1% and 21.7% in carrot slices treated with hot aqueous solution of 2% citric acid and with hot aqueous solution of 2% sodium chloride respectively at 12 days of storage. On the 12 th day of storage, fresh-cut carrot treated with hot aqueous solution of 2% citric acid scored 7.3 and the rest of the sample scored less than 4.5 (indicate as unacceptable) in overall acceptability. Carrot slices treated with hot aqueous solution of 2% citric acid and 2% sodium chloride retained a minimum number of TBC and delayed changes in WI, external colour and beta carotene content compared to without heat-treated carrot slices.

Correlation and path analysis was executed in twentythree tomato genotypes for thirteen yield contributing characters. The correlation coefficients were ascertained to detect the studied character interrelationships. Yield (t/ha) was showed positive and highly significant correlated with yield per plant(r =0.99) followed by individual fruit weight (r =0.72), fruit breadth (r =0.67), number of locules per fruit (r =0.67) and pericarp thickness (r =0.66) which indicated that yield could be enhanced by improving these traits. Path coefficient analysis indicated the cause and effect relationship among yield (t/ha) and its components. Yield per plant exhibited the highest positive direct effect (1.018) on yield (t/ha) followed by the number of flowers per inflorescence (0.212) and pericarp thickness (0.155). Fruit breadth (-0.279) showed the highest negative direct effect on yield (t/ha) but it had a highly significant positive correlation with Yield (t/ha) (r=0.67). High direct effect on yield (t/ha) was revealed by the characters that indicated direct selection in favor of these traits might be feasible. Selection based on these characters has great potential for improving yield (t/ha). The studied characters explained almost all variability towards yield signified by considerably very low residual effect (0.004606).

Half of each treatment was kept at (6±1°C and 50±5% RH) and the other half was kept at ambient conditions (25±3°C and 60±5% RH). LDPE bag or PE cling film has a great effect to retain firmness and reduce weight loss of cauliflower in both storage conditions. Respiration rate, rot incidence and changes of colour values (lightness and hue angle) was reduced significantly for the cauliflowers packed in LDPE bag or wrapped with PE cling film stored in a refrigerator than that of control (without packaging) and all packaging techniques stored at ambient condition throughout the storage period. Initially, acidity, TSS and ascorbic acid content were 0.26%, 4.7° Brix and 58.7 mg 100g-1 , respectively. Ascorbic acid content was reduced severely in the cauliflower stored in ambient conditions than that stored in a refrigerator. Cauliflower wrapped with PE cling film and packed in an LDPE bag (1% perforation) stored in a refrigerator (6±1°C and 50±5% RH) could retain white colour, good sensory quality, firm and fresh curds with minimum loss in weight, texture and disease incidence up to 18 days and 16 days, respectively.

This experiment was carried out to increase the shelf life and maintaining the quality of mango (... more This experiment was carried out to increase the shelf life and maintaining the quality of mango (Mangifera indica) fruits. There were two factors. Factor A: postharvest treatments with six levels (1. untreated (control), 2. washing with chlorine, 3. dipping (5 minutes) in calcium chloride (CaCl 2), 4. dipping (5 minutes) in bavistin and rinse in clean water, 5. hot water treatment and 6. tap water wash) and factor B: packaging technique with five levels (1. without packaging (control), 2. perforated poly bag (0.5%), 3. non-perforated poly bag, 4. plastic crate and 5. corrugated fibre board carton). The fruits treated with chlorine wash, tap water wash, hot water treatment, dipping in calcium chloride and bavistin were significant difference on chemical parameter (total sugar content, vitamin-C, total titrable acidity and total soluble solid) of mango. Treated fruits performed less disease incidence compared to without treated fruits. Non-treated fruits were attacked by the sunken black spots on the surface of the fruits as well as anthracnose (Colletotrichum gloeosporioides). In case of packaging technique, fruits packed in different packaging materials (like corrugated fibre board carton, plastic crate, perforate and non-perforated polyethylene bag) had the maximum shelf life, lower physiological loss in weight and less disease incidence than without package. Among the different packaging materials, fruits packed in corrugated fibre board carton had the maximum shelf life (13.02 days), lower physiological loss in weight (4.11%) and less disease incidence (1.12%) without excessive deterioration compared to others. The shelf life of mango could be extended up to 5 days by hot water treatment and packed in. corrugated fibre board carton compared to others. The color and quality of mango was very better in treated fruits compared to non-treated fruits.

Following treatment, fresh-cut carrot slices were kept in a polypropylene (PP) box and stored in a refrigerator (4±1°C and 50±5% RH) for 12 days. The effectiveness of the treatments in extending shelf life was evaluated by determining respiration rate, firmness, weight loss, external colour, whiteness index (WI), some chemical parameters (ascorbic acid content, TSS, acidity, pH, total sugar, reducing sugar and beta carotene), total bacterial count (TBC) and sensory quality. The highest increment of WI (48.4%) was observed without heattreated carrot slices. On the other hand, WI was increased by 12.1% and 21.7% in carrot slices treated with hot aqueous solution of 2% citric acid and with hot aqueous solution of 2% sodium chloride respectively at 12 days of storage. On the 12 th day of storage, fresh-cut carrot treated with hot aqueous solution of 2% citric acid scored 7.3 and the rest of the sample scored less than 4.5 (indicate as unacceptable) in overall acceptability. Carrot slices treated with hot aqueous solution of 2% citric acid and 2% sodium chloride retained a minimum number of TBC and delayed changes in WI, external colour and beta carotene content compared to without heat-treated carrot slices.
