The real-time, continuity, and accuracy of blast furnace stockline information are of great significance in reducing energy consumption and improving smelting efficiency. However, the traditional mechanical measurement method has the problem of measuring point discontinuity, while the radar measurement method exhibits problems such as weak anti-interference ability, low accuracy, and poor stability. Therefore, a high-dimensional, spatial feature stockline detection method based on the maximum likelihood radial basis function model (MLRBFM) and structural dynamic self-optimization RBF neural network (SDSO-RBFNN) is proposed. Firstly, the discrete time series joint partition method is used to extract the time dimension periodic features of the blast furnace stockline. Based on MLRBFM, the high-dimensional spatial features of the stockline are then obtained. Finally, an SDSO-RBFNN is constructed based on an eigen orthogonal matrix and a right triangular matrix decomposition (QR) direct clustering algorithm with spatial–temporal features as input, so as to obtain continuous, high-precision stockline information. Both the simulation results and industrial validation indicate that the proposed method can provide real-time and accurate stockline information, and has great practical value for industrial production.

The stockline, which describes the measured depth of the blast furnace (BF) burden surface with time, is significant to the operator executing an optimized charging operation. For the harsh BF environment, noise interferences and aberrant measurements are the main challenges of stockline detection. In this paper, a novel encoder–decoder architecture that consists of a convolution neural network (CNN) and a long short-term memory (LSTM) network is proposed, which suppresses the noise interferences, classifies the distorted signals, and regresses the stockline in a learning way. By leveraging the LSTM, we are able to model the longer historical measurements for robust stockline tracking. Compared to traditional hand-crafted denoising processing, the time and efforts could be greatly saved. Experiments are conducted on an actual eight-radar array system in a blast furnace, and the effectiveness of the proposed method is demonstrated on the real recorded data.

The paper presents a synergistic approach for height tracking within a blast furnace (BF). The Frequency Modulated Continuous Wave (FMCW) radar has been employed to measure the height and surface profile of the burden surface. However the radar signal is easily disturbed, by the radar anomalies, during the process of continuous measurement. The data from rotating chute and charging switch provide information on contextual relevance with radar anomalies. An anomaly detection models has been developed to increase the measurement accuracy by utilizing contextual information. The approach has been validated on real BF. The root mean squared (RMS) error in the measured height is reduced by 17% when using the proposed approach compared to the case without it. The results suggest that the proposed approach successfully adapts to changes in the pattern and characteristics of the burden surface.

This study aimed to analyze the use of stocklab game to improve students' understanding of the stock market. This research was a quasi-experimental study with a nonequivalent control group design. The object of this study were students of class X IPS in MAN Surabaya. Class X IPS 2 was determined as the experimental class while class X IPS 3 as the control class. Both classes were given the same treatment using cooperative learning methods make a match type and numbered head together, however in the experimental class, games were given in the form of stocklab games. The analysis technique used to test the research hypothesis was one way ANOVA. Hypothesis tested by comparing the pre-test and post-test scores in both classes. Based on the analysis results, it was known that there were differences in students' understanding of the control class and the experimental class, where the understanding of the experimental class students tend to be better than students in control class. In addition, students also tend to understand more stock market terms.

Tidak dapat dipungkiri bahwa Pasar Modal memiliki peran penting bagi perekonomian suatu negara karena pasar modal menjalankan dua fungsi, pertama sebagai sarana bagi perusahaan untuk mendapatkan dana dari masyarakat pemodal (investor). Dana yang diperoleh dari pasar modal dapat digunakan untuk pengembangan usaha, ekspansi, penambahan modal kerja dan lain-lain, kedua pasar modal menjadi sarana bagi masyarakat untuk berinvestasi pada instrumen keuangan seperti saham, obligasi, reksa dana, dan lain-lain. Dengan demikian, masyarakat dapat menempatkan dana yang dimilikinya sesuai dengan karakteristik keuntungan dan risiko masing-masing instrumen. Tingkat pemahaman (literasi) masyarakat Indonesia terhadap pasar modal dan tingkat utilitas produk pasar modal masih sangat rendah dan yang terkecil dibandingkan dengan lima industri jasa keuangan lainnya (keuangan, asuransi, perbankan, pegadaian, pensiun) di Indonesia. Oleh karena itulah Pengabdian Masyarakat (P3M) STIE Trisakti memberikan edukasi awal kepada siswa-siswi SMA Muhammadiyah 25 Pamulang dengan tujuan turut merubah pola pikir saving society menjadi investing society. Metode yang dilakukan dengan memberikan pengenalan teori dasar Pasar Modal oleh dosen dan praktik stocklab games oleh mahasiswa Galvest TSM menjadikan kelompok siswa XII tertarik meresponi setiap kegiatan. Hasil dari pengenalan pasar modal kepada siswa adalah sejak dini sudah dikenalkan nabung saham, agar kedepan generasi milenial Indonesia menuju investing society.

The operation of the furnace depends largely on the handling of gas distribution which in-turn is reliant on the burden surface profile. Measurement of burden profile has been a challenge because of the harsh conditions inside the furnace. Phased array radar will suffice this purpose with no moving parts; however, it imposes its own challenges. One of them is measurement of extremely short distances as the stockline in the blast furnace is just few meters away from the topmost part. Unlike conventional radar where the target is kilometre away the short distance measurement involves with time measure din nano seconds with pico-seconds resolution to achieve the desired accuracy. This paper implements a method for ultra-short distance measurement using radars for blast furnace application in steel plant.

Detailed geological mapping was carried out in the Bandipur-Gondrang area of Tanahun district to clarify the geological set up and stratigraphy of the area. Wherever possible, geological mapping is based on stratigraphic units proposed by Stocklin and Bhattarai (1977) in central Nepal and the present mapping is the west ward continuation from Mugling-Banspani area (Paudyal and Paudel, 2011). The study area comprises low grade metasedimentary rocks of Nawakot Complex. The rock succession of the area are divided into six formations as the Kunchha Formation, the Fagfog Quartzite, the Dandagaon Phyllite, the Nourpul Formation with four members, the Dhading Dolomite and the Benighat Slates in stratigraphic upwards. The former four formations belong to Upper Nawakot Group and the remaining one belongs to the Lower Nawakot Group of Nawakot Complex (Stöcklin and Bhattarai, 1977). Based on lithology, the Nourpul Formation is divided into the Purebensi Quartzite, the Amdanda Phyllite, the Labdi Khola Member and the Bandipur Slate from bottom to top respectively. The Purebensi Quartzite is lithologically distinct in the field; the Labdi Khola Member is significant with copper and iron mineralization in the area, and the Bandipur Slate is also significant with roofing quality slate, however, the Amdanda Phyllite is mapped as an intervening member between significant lithologies. The rocks of the present study area consist of several sedimentary structures like mud cracks, ripple marks, graded bedding and cross and parallel laminations. A broad Ghumaune- Gondran Synclinorium is mapped in the area. In addition to this, several anticlines and synclines are also mapped in the study area. Jalbhanjyang Thrust has brought the older metasedimentary rocks of the Nawakot Complex over the younger rocks of the same Complex. Some corrections are recommended over the distribution of previously shown lithological units by Stocklin and Bhattarai (1977) around the Ghumaune-Bhut Khola section.

The stakeholder management framework of the 1980s and the triple bottom line framework of the 1990s strengthened corporate social responsibility but these frameworks could not bring about fundamental change in the role of businesses in society in relation to value creation. Hence, by the beginning of the present century, drawing on the ‘Sustainable Value’ and ‘Shared Value’ business models, the selected Australian banking and property organisations are striving to leverage on business strategies for generation of social and economic values. However, the Australian academic literature and industry reports demonstrate limited contributions to the sustainable and shared value literature, and hence, failing to support and deliver a comprehensive business model. To fill this conceptual and practical gap in the Australian industrial context, this study is undertaken with a view to recommend an alternative business model to integrate socioenvironmental issues and opportunities into core business strategy. Research objectives of the underlying study are to: a) explore the adoption of components of the applied sustainable value and shared value business models by Australian banking and property organisations for social and economic value creation; and b) empirically develop an alternative business model for the Australian banking and property industries based on emerging thematic components from industry-wide interview responses. Based on the interpretive paradigm, this study has adopted a qualitative multiple case study design to conduct semi-structured open-ended face-to-face interviews. The cases (n=8) in the banking and property industries have been selected through a purposive critical sampling approach. A thematic NVivo analysis was conducted based on four thematic components derived from the applied sustainable and shared value business models, namely clean technology, sustainability vision at the bottom of the pyramid, reconceiving of products/services and redefining of the value chain. This study explores how the selected Australian banking and property organisations are utilising various thematic components for social and economic value creation in addition to other components (i.e. customer/stakeholder engagement, community resilience) not otherwise categorically mentioned within both the above-mentioned models. The major findings show a number of industry-wide differences, which include a) banking organisations predominantly leverage sustainability based on product/service innovation at the bottom of the pyramid level, and b) property organisations predominantly leverage environmental sustainability based on the application of clean technology through redefining the value chain. The primary interview data findings suggest that the selected Australian sustainable and shared value organisations also emphasise the co-creation of value based on their engagement with customers, stakeholders, and communities. The secondary data findings suggest that the selected Australian property organisations have ensured a higher increase in net profit after tax and return on equity compared to the banking organisations. The secondary data further suggest that organisations (i.e. Suncorp, Charter Hall, Company X, Stockland) which used the combination of the elements of sustainable and shared value business models performed better in terms of profitability (i.e. economic value) than the organisations which only used either the sustainable value (ANZ, Lendlease) or the shared value (Bendigo, NAB) model. The only exception being Stockland, which experienced a slight decrease in the return on equity during the 2014- 18 period inspite of almost triple digit increase in net profit during the above-mentioned period. In terms of social value, the secondary data further suggest that the selected banking and property organisations have undertaken quite considerable social and community investments while leveraging on the components of various business models. The main recommendation of this study is an empirically developed alternative business model for value co-creation based on two new thematic components, which are customer/stakeholder engagement and community resilience that emerged from the industry case interviews. The significance of the study lies in the fact that all future academic researchers and practice managers should be able to implement the recommended business model for value co-creation to enhance social and economic value. One of the other major implications of the study lies in its application of a stakeholder-centric (i.e. customers, communities) value creation model by Australian banking organisations which have recently gone through the Financial Services Royal Commission investigation. The future theoretical implications of this study on value cocreation can be considered in terms of a better understanding of stakeholder theory (encompassing customers and communities) and agency theory (encompassing valueseeking organisational agents) with respect to the banking and property industry in Australian context.
