Abstract: Using the stochastic production frontier approach, the technical efficiency of splint and veneer industry of Kerala was analysed. Alianthus triphysa, Bombax ceiba and Melicope lunu-ankenda (Gaertn.) are still the main raw material species. But the demand of rubber wood as an alternate raw material is now rising. The mean technical efficiency(TE) of this sector was only 0.6. This paper discusses the social and other industrial reasons for the low efficiency in this sector. A migrant, unskilled workforce is possibly bringing down the efficiency. Coupled with this, the employment of obsolete techniques and technologies are the main reasons identified for the low TE scores. However, there many industries within this cluster which had high individual TE scores. This reinforces the scope for improvement within this industry. The marked presence of educated, young entrepreneurs is a definite indication of this industry ' s continued potential to provide sustainable livelihoods in the future.

Abstract: Chir pine is commercially tapped for oleoresin. The oleoresin yeild is affected by number of factors. The experiment was conducted to investigate the relationship of morphological parameters and climatic factors with oleoresin yield. The diameter at breast height, height, needle diameter, needle length and bark thickness showed a significant relationship with oleoresin yield. The number of primary branches, crown length has not shown significant relationship with oleoresin yield. The oleoresin yield was highly correlated with the temperature followed by evapotranspiration and sunshine hours. The factors like rainfall, humidity showed non-significant correlation with oleoresin yield; however they have influenced temperature and evapotranspiration.

Abstract: Prosopis cinerea (Leguminasae) is a hardy tree species and mostly grown in arid and semi arid zones. In Chattisgarh semiarid conditions appear in Entisols just after the rainy seasons. A nursery trial was conducted using Entisols supplemented by FYM in different ratio viz; 0(T1), 25 (T2), 33 (T3), 50 (T4), 67 (T5), 75 (T6) and 100 per cent (T7). The emergence of seedling was 64.3 per cent in T1, T5, and T6 while 57.1 percent in T2, T3,and T4, with minimum in T7 (42.9%). Survivorship of seedling was ranged 81.3 and 88.9 percent. The growth in shoot, root length and dry matter accumulation was highest in T7 (Pure FYM) followed by T6 (75% FYM) with decreasing trend as share of FYM get decreased till T1(Pure soil). The observations were found statistically insignificant between T1 to T5 and T5 to T7. The positive correlation among soil and plant parameters showed that availability of nitrogen in soil played very significant role for growth of stem, leaves and roots, while availability of phosphorus promote growth in stem and roots only. There was strong negative relationship between organic carbon and emergence seedlings, resulted the least emergence in T7 (42.9%) due to toxicity causes by organic matters. Thus over all the application of FYM particularly in the ratio of 1:2 and 1:3 with Entisols in trreatment T5 and T6 respectively were found better for raising the seedling and plants Prosopis cinerea.

Abstract: Investigations on mycorrhizal status of seedlings of four agroforestry tree species viz., Acacia nilotica, Albizia lebbeck, Pongamia pinnata and Sesbania grandiflora grown in six social forestry nurseries in terms of percentage of colonization, number of resting spores in rhizosphere and presence of arbuscules, vesicles and mycelluim in the colonized roots was determined. Percentage of colonization, spore population and nodulation of seedlings varied with the tree species as well as soil. All the three characteristic structures of AM fungi viz., Glommus fasciculatum, Gl. macrocarpum, Gl. dussi, Acaulospora delicate, Gigaspora sp. and Scutellospora sp. were evaluated under pot culture conditions to select an efficient strain. All these strains supported good growth of saplings compared to uninoculated control. G. fasciculatum was selected for further investigations in view of its superior support of growth of seedlings.

Abstract: The study related to density and regeneration in response to anthropogenic disturbance along the altitudinal and horizontal gradients in sacred forests of Trikuta hills in J & K showed a gradual decrease in anthropogenic disturbance level with the increase in altitudinal gradient and horizontal distance from the main track leading to shrine at each forest stand. On the basis of point scaling of different parameters, the higher altitudinal stand (2000-2200m amsl) represented undisturbed stand, while intermediate (1400-1600 m asl) and lower altitudinal stands (800-1000m amsl) were moderately disturbed. The density of tree species also showed an increasing trend with the increase in altitude with highest density of 10.83 individuals/100m? at stand lll and lowest of 7.5 individuals/100m? at stand I. In case of horizontal blocks for all the stands, density showed an increasing trend with the decreasing disturbance level. Seedling and sapling density at lower altitude indicate future generation of mixed species, intermediate stand revealed dominance of Pinus roxburghii, while at higher altitude Pinus roxburghii and Quercus leucotricophora have promising future.

Abstract: Based on the floristic survey conducted, Decalepis aryalpathra (Joseph & Chandras.) Vent., an endemic and endangered species of southern Western Ghats found to be distributed in (1) near Vellachipudavu, on the way to Aduppukal mottai, (2) Oothu, above Amman Kovil, (3)Visthara mottai, above Naraikadu and (4) Thaipatham mottai, above Nambi Koil of Kalakad Mundanthurai Tiger Reserve. A total of 932 individuals were recorded from the sample plots established in these four sites. Among these more number of individuals were recorded from Thaipatham followed by Visthara mottai, Vellachipudavu. Asparagus gonocladus, Eriocaulon enisforme, Exacum atropurpureum, Hedyotis purpurascens, Osbeckia wightiana etc. are some of the associated species of D.arayalpathra. The tubers of this species are found to be eaten up by wild boars at Vellachipudavu. Though there are many individuals recorded, the population are still limited and fragmented extensively. The lag in the regeneration as well as continuous harvest of tubers for medicinal use leads to the drastic reduction in the population size of this species.

Abstract: Luc Grare: First off, it ' s the same now as it was a year ago: REC supports fair trade without state interventio. But Chinese companies have apparently been selling products at dumping prices, at least according to research conducted by the European Commission. We manufacture in Singapore, so we ' re not affected, but are the punitive duties an advantage for us? Of course they are. The price pressure that has ruined the whole industry in recent years has been noticeably reduced. As recently an year ago, project developers could just dictate the prices because there was always a firm that would supply panels at a good price, say because it was sitting on a large stock. But that ' s over now - and obviously that is a good thing for us.

Abstract: Energy storage requires a systemic approac. As the system still has a relatively high degree of flexibility, which is more cost effective to harness than new storage systems are the most expensive solution. Grid-balancing options are cheaper. In addition, output can be restricted with in the existing pool of power plants. Load management is another option. These possibilities are significantly under-exploited. Energy-storage systems are further down the road.

Keywords: Robust, Affine-Invariant Line Matching, High Resolution Remote Sensing Images.
Abstract: Point-based matching methods usually hold limitation in dealing with low texture scenes. In this paper, a robust affine-invariant lines matching method is proposed. The method commences with line segments extraction. All the extracted line segments are grouped into salient lines and general lines. Accordingly, the matching procedure includes salient lines matching and general lines matching. In salient lines matching, affine-invariants are calculated and the matched salient lines correspondences are the basis of the general lines matching. Each general line is clustered into a matched salient line according to a certain rule. Taking each salient line as the root , together with all the general lines clustered to it, a control network is constructed. Finally, the general lines matching procedure is performed between the two subnetworks whose roots are correspondences. Experimental results show that our proposed method can successfully process local distortion and improve the matching performance in low texture areas.

Abstract: Geometric registration of multiple-source data is of great value for fusion processing and is very beneficial for the research of desert ecosystems. A lidar point cloud and optical image are two typical data that need to be integrated for data assimilation and information retrieval. This paper aims to solve the registration problem of aerial imagery and airborne lidar data in deserts, such as the Sahara in Africa and Gobi in China, we observe that there are unevenly distributed desert bushes, which can be used as cues for registration. In this paper, we propose a registration approach using the centroids of bushes as registration primitives. This approach employs similar triangles created from both centroids as the evidence for matching and verifies the registration by the RANSAC algorithm. Experiments using data taken from the Dunhuang Gobi Desert in China show the registration surface model visually, and at the same time quantifies the deviation error, which corrobates that the proposed registration method is effective and feasible in desert areas.

Keywords: Optical Images, Lidar Data, Accuracy Assessment.
Abstract: Photogrammetry and lidar are two technologies complementary for 3D reconstruction. However, the problem is that the current registration methods of optical images with lidar data cannot satisfy all the requirements for the fusion of the above two technologies, especially for close-range photogrammetry and terrestrial lidar. In this paper, we propose a novel method for registration of optical images with terrestrial lidar data, which is implemented by minimizing the distances from the photogrammetric matching points to terrestrial lidar data surface, with the collinearity equation as the basic mathematical model. One advantage of this method is that it requires no feature extraction and segmentation from the lidar data. Another advantage is that non-rigid deformation caused by lens distortion can be eliminated through the use of bundle adjustment similar to self-calibration. In addition, experiments with two different data sets show that this method cannot only eliminate the influence of certain gross errors, but also offer high accuracy of 3 mm to 5 mm. Therfore, the proposed registration method is proved to be more effective, accurate, and reliable.
